Impella® 5.0 with the Impella® Console I 1 Warnings and Cautions Warnings.................................................................................................... 1.1 Cautions.....................................................................................................1.2 Warnings Warnings The Impella® 5.0 System has not been qualified in the United States (US) through clinical studies for long term use (longer than 6 hours), for example, as a bridge to transplant or for pending recovery of the natural heart. Warnings alert you to situations that can cause death or serious injury. The red symbol appears before warning messages. Fluoroscopy is required to guide placement of the Impella® 5.0 Catheter. The small placement guidewire must be reliably observed at all times. Avoid manual compression of the inlet, outlet, or sensor areas of the cannula assembly. Avoid overinserting the catheter and possibly impinging the catheter tip against the walls of the vasculature, atrium, or ventricle. Do NOT advance or withdraw the Impella® 5.0 Catheter against resistance without using fluoroscopy to determine the cause of the resistance. Doing so could result in separation of the catheter or guidewire tip, damage to the catheter or vessel, or ventricular perforation. Be sure that the stopcock on the repositioning sheath is always kept in the closed position. Significant bleed back can result if the stopcock is open. The sterile components of the Impella® 5.0 System can be used only if the sterilization indicators show that the contents have been sterilized, the packaging is not damaged, and the expiration date has not elapsed. Do NOT resterilize or reuse the Impella® 5.0 Catheter. It is a disposable device and is intended for single use only. Reuse, reprocessing, or resterilization may compromise the structural integrity of the catheter and/or lead to catheter failure which, in turn, may result in patient injury, illness, or death. Retrograde flow will occur across the aortic valve if the Impella® 5.0 Catheter is set at performance level P0. The infusion pump supplied by Abiomed must NOT be used in conjunction with any products other than Impella® products. Do NOT use saline in the purge system. Do NOT use alcohol-based fluids for lubrication. Do NOT use an Impella® 5.0 System if any part of the system is damaged. To prevent the risk of explosion, do NOT operate the Impella® 5.0 System near flammable anesthetics. If at any time during the course of support with the Impella® 5.0 Catheter, the Impella® Console alarms “Low Purge Pressure,” follow the instructions presented in “Purge System Troubleshooting” in Section 5 of this manual.

Do NOT subject a patient who has been implanted with an Impella® 5.0 Catheter to magnetic resonance imaging (MRI). The strong magnetic energy produced by an MRI machine may cause the Impella® 5.0 System components to stop working, and result in injuries to the patient. An MRI may also damage the electronics of the Impella® 5.0 System. During defibrillation, do NOT touch the Impella® 5.0 Catheter, cables, or Impella® Console. Cautions Cautions Cautions indicate a situation in which equipment may malfunction, be damaged, or cease to operate. The yellow symbol appears before caution messages. Handle with care. The Impella® 5.0 Catheter can be damaged during removal from packaging, preparation, insertion, and removal. Do NOT bend, pull, or place excess pressure on the catheter or mechanical components at any time. Patients with aortic stenosis or other abnormal aortic valve performance may be compromised by the use of the Impella® 5.0 Catheter. Patients with aortic valve disease should be observed for aortic insufficiency. Use only original accessories and replacement parts supplied by Abiomed. Refer to the instructions for use supplied with the infusion pump being used before using the infusion pump with the Impella® 5.0 System. To troubleshoot purge system alarms not listed in this manual, refer to the appropriate infusion pump instructions for use manual. Holding down the ON key on the Impella® Console for longer than 3 seconds during operation will cause the Impella® Console to go into emergency stop mode. The performance level of the Impella® 5.0 Catheter is automatically set to P2 during zeroing if the catheter is operating above P0. Performance level remains at P2 after zeroing and does not automatically return to its prior setting. When conducting the Impella® Console function test as part of preventive maintenance, if a pressure value of 50 (± 4) mmHg does not appear or the speed is not within the specified range of 24,000 ± 1,000 revolutions per minute (rpm), do NOT use the Impella® Console. Do NOT use damaged or contaminated connector cables. To prevent device failure, do NOT start the Impella® 5.0 Catheter until the placement guidewire has been removed.

The catheter is inserted through the femoral artery and into the left ventricle. (See Figure 3.1.) Figure 3.1 Impella® 5.0 Catheter in the Heart When properly positioned, the Impella® 5.0 Catheter delivers blood from the inlet area, which sits inside the left ventricle, through the cannula to the outlet opening in the ascending aorta. Physicians and device operators monitor the correct positioning and functioning of the Impella® 5.0 Catheter on the display screen of the Impella® Console. This section describes the components of the Impella® 5.0 System. Reusable System Components The Impella® 5.0 System consists of the following reusable components: • Impella® Console—provides the user interface, alarm indications, and portable battery • Impella® Power Supply and Power Supply cable—for continuous operation of the console • Infusion pump—for purging the Impella® 5.0 Catheter • Pressure transducer cable • Pump test plug Impella® 5.0 with the Impella® Console 3.1 Single-use System Components The system also includes the following single-use components: • Impella® 5.0 Catheter • Impella® Combitrans-Monitoring Set (CM-Set) • 0.025 inch, 260 cm placement guidewire • Connector cable • Purge tubing System Configuration Figure 3.2 illustrates the Impella® 5.0 System components.

Figure 3.3 illustrates the Impella® 5.0 Catheter. Table 3.1 describes each component from the pigtail at one end to the check valve on the other end. Check Valve Pressure Reservoir Red Impella® Plug Infusion Filter Clear Sidearm Catheter Shaft Repositioning Unit Pigtail Inlet Area Cannula Differential Pressure Sensor Outlet Area Motor Housing Figure 3.3 Impella® 5.0 Catheter Table 3.1 Impella® 5.0 Catheter Components Component Description Pigtail The 6 Fr pigtail is attached to the cannula at the distal end of the inlet area. It assists with stabilizing the catheter in the correct position in the left ventricle and decreases the amount of ectopy that could be caused by a foreign body in the ventricle. Inlet area The inlet area, located at the distal tip of the cannula, has five openings (windows) that allow blood to be drawn into the inlet and channeled through the cannula. Cannula The 21 Fr cannula has a spiral-shaped reinforced body that is shaped in a 35-degree angle. The cannula is made of nitinol and covered in polyurethane. • Nitinol provides the cannula with flexibility and memory, allowing it to conform across the aortic valve. • Polyurethane provides a smooth surface for atraumatic positioning and reduced risk of damage to the aortic valve. Impella® 5.0 with the Impella® Console 3.3 Table 3.1 Impella® 5.0 Catheter Components (cont’d) Component Description Differential pressure sensor A sensor that measures the pressure difference between the inside and outside of the cannula. The pressure value is used for positioning during placement and for monitoring flow and position during catheter operation. Outlet area The proximal end of the cannula is attached to the outlet area where the blood exits the cannula. Motor housing The motor housing is 21 Fr in diameter and consists of an encapsulated motor. Catheter shaft A 9 Fr catheter shaft is located between the motor housing and . the red Impella® plug. The lumen of the catheter shaft contains a purge lumen, an electrical cable, and a differential pressure measurement cable. The catheter shaft has longitudinal and transversal marks: • The longitudinal mark along the inner radius shows correct position of the 0.025 inch, 260 cm placement guidewire once backloaded on the Impella® 5.0 Catheter. • The transversal marks at 1 cm intervals with numbers every 5 cm aid in proper positioning. Repositioning unit The repositioning unit consists of a sheath and an anticontamination sleeve with an anchoring ring. • The 9 Fr sheath (11 Fr outer diameter) with hemostatic valve is located on the catheter shaft and allows repositioning of the catheter. • The anchoring ring of the anticontamination sleeve secures the sheath to the catheter. Red Impella® plug The red Impella® plug has a clear sidearm and contains memory that retains operating parameters in case the patient needs to be transferred to another console. The plug connects the catheter to the Impella® Console through a connector cable. Clear sidearm The clear sidearm is attached to the infusion pump to purge the Impella® 5.0 Catheter. It leads to the infusion filter, the pressure reservoir, and the check valve. Infusion filter The infusion filter prevents bacterial contamination and air from entering the purge lumen. Pressure reservoir The pressure reservoir includes a flexible rubber diaphragm that provides additional filling volume by means of an expansion chamber during purge solution change. Check valve The yellow check valve ensures that purge fluid does not flow in the reverse direction when the purge solution is exchanged. Differential Pressure Sensor The Impella® 5.0 Catheter has an electronic differential pressure sensor located at the proximal end of the 21 Fr cannula (see Figure 3.4). The purpose of the pressure sensor is to generate the placement signal, which is used by operators, the console’s placement monitoring screen, and alarm algorithms to monitor the position of the Impella® 5.0 cannula relative to the aortic valve. 3.4 Instructions for Use & Clinical Reference Manual 3The Impella® 5.0 System The pressure sensor is a flexible membrane integrated into the cannula (see Figure 3.4). One side of the sensor is exposed to the blood pressure on the outside of the cannula and the other side is exposed to the pressure of the blood inside of the cannula. The sensor generates an electrical signal proportional to the difference between the pressure outside the cannula and the pressure inside. This signal is displayed on the Impella® Console as the placement signal. Differential Pressure Sensor Aortic Pressure Sensor Flow from Ventricle Ventricular Pressure Flow to Aorta Membrane Cannula Aortic Valve Figure 3.4 Differential Pressure Sensor The pressure sensor membrane flexes when the pressure on one side is different from the pressure on the other side, and the electrical properties of the membrane change when it flexes. This allows the sensor to generate an electrical signal proportional to how much the membrane is flexed, and thus proportional to the difference between the pressure on the outside of the cannula and the pressure inside. When the Impella® 5.0 Catheter is placed in the correct position across the aortic valve, the top (outer surface) of the sensor is exposed to the aortic pressure and the bottom (inner surface) of the sensor is exposed to the ventricular pressure. Therefore, the placement signal is approximately equal to the difference between the aortic pressure and the ventricular pressure (see Figure 3.5). Systole Blood Pressure (mmHg) 120 Aortic pressure 80 Pressure difference Diastole Left ventricular pressure 0 Time PDifferential = PAO - PLV Pressure difference (PDifferential ) Left ventricular pressure (PLV ) Aortic pressure (PAO ) Figure 3.5 Electrical Signal Generated by the Cardiac Cycle Impella® 5.0 with the Impella® Console 3.5 When the Impella® 5.0 Catheter is correctly positioned across the aortic valve, the changes in pressure associated with the cardiac cycle result in a pulsatile placement signal (see Figure 3.6). During diastole (time zero in Figure 3.5), the large pressure difference between the aorta and the left ventricle creates a large electrical signal. Then at the peak of systole, when the aortic valve opens, the pressure difference between the aorta and the left ventricle—and thus the electrical signal—is zero. Thus, the continual pressure changes associated with the cardiac cycle produce the pulsatile (up and down) waveform seen on the Impella® Console display.

As a result, the pressure on either side of the sensor membrane is the same, resulting in a flat placement signal (see Figure 3.7).

The purge pressure display ranges from 0 to 1000 mmHg. A warning appears if purge pressure falls below 300 mmHg or exceeds 700 mmHg. P-Perf P9 LV4509 Flow [L/min] 98% 5.0 Purge Pressure [mmHg] 472 < < 10 s Figure 4.6 Purge Pressure Screen 4.8 Instructions for Use & Clinical Reference Manual Motor Current (A) 4Using the Impella® Console Motor current is a measure of the energy intake of the Impella® 5.0 Catheter motor. The energy intake varies with motor speed and the pressure difference between the inlet and outlet areas of the cannula. It is important to monitor the motor current waveform (see Figure 4.7) because it provides information about the catheter position relative to the aortic valve. When the Impella® 5.0 Catheter is positioned correctly, with the inlet area in the ventricle and the outlet area in the aorta, the motor current is pulsatile because the pressure difference between the inlet and outlet areas changes with the cardiac cycle. When the inlet and outlet areas are on the same side of the aortic valve, the motor current will be dampened or flat because there is little or no pressure difference between the inlet and outlet areas.

T he “Ready to Insert” screen will switch to the placement signal screen within 10 seconds. 5.8 Instructions for Use & Clinical Reference Manual Inserting the Impella® 5.0 Catheter Fluoroscopy is required to guide placement of the Impella® 5.0 Catheter. The small placement guidewire must be reliably observed at all times. Avoid manual compression of the inlet, outlet, or sensor areas of the cannula assembly. Do NOT kink or clamp any part of the Impella® 5.0 Catheter. Handle with care. The Impella® 5.0 Catheter can be damaged during removal from packaging, preparation, insertion, and removal. Do NOT bend, pull, or place excess pressure on the catheter or mechanical components at any time. 1. Identify the femoral artery and perform a cut-down of 3 to 5 cm. Use Fluoroscopy for Placement Impella® 5.0 Catheter performance will be compromised if correct placement cannot be confirmed. While other imaging techniques, such as transesophageal echocardiography (TEE), can help confirm the position of the Impella® 5.0 Catheter after placement, TEE does not allow visualization of the entire catheter assembly or guidewire and is inadequate for reliably placing the Impella® 5.0 Catheter across the aortic valve. 2. E xpose the femoral artery. Wrap vessel loops, one distal and one proximal to the subsequent point of incision, one and a half times around the artery. Make the vessel loops as far apart as possible (see Figure 5.14).

Impella® 5.0 with the Impella® Console 5.9 5 Using the Impella® 5.0 System NOTE – Proper surgical procedures and techniques are the responsibility of the medical professional. The described procedure is furnished for information purposes only. Each physician must evaluate the appropriateness of the procedure based on his or her medical training and experience, the type of procedure, and the type of systems used. Impella® 5.0 Catheter Use in Open Heart Surgery 4.Make the incision as close as possible to the distal loop. Insert a 6 Fr diagnostic catheter with no side holes (AL1 or Multipurpose without side holes recommended) over a diagnostic 0.035 inch or 0.038 inch guidewire into the left ventricle. If the Impella® 5.0 Catheter is used in the OR as part of open heart surgery, manipulation may be performed only through the 9 Fr steering catheter. Direct manipulation of the catheter assembly through the aorta or ventricle may result in serious damage to the Impella® 5.0 Catheter and serious injury to the patient. 5.Remove the diagnostic guidewire and exchange it for the supplied 0.025 inch placement guidewire. 6. H old tension on the proximal vessel loop to prevent bleeding. Straighten the blue pigtail and thread it over the 0.025 inch placement guidewire (see Figure 5.15). Wet the cannula with sterile water and backload the catheter onto the placement guidewire. One or two people can load the catheter on the guidewire. 1cm Inlet Catheter (with marking) Avoid Damaging Inflow Area During placement of the Impella® 5.0 Catheter, take care to avoid damage to the inflow area while holding the catheter and loading the placement guidewire. Outlet Pigtail Guidewire Sensor Figure 5.15 Guidewire Placement One-person technique a.Advance the placement guidewire into the Impella® 5.0 Catheter and stabilize the cannula between the fingers. This prevents pinching of the inlet area. The placement guidewire must exit the outlet area on the inner radius of the cannula, as shown in Figure 5.15, and align with the straight black line on the catheter. The cannula can be hyperextended as necessary to ensure the placement guidewire exits on the inner radius of the cannula. Two-person technique b.The scrub assistant can help stabilize the catheter by holding the catheter proximal to the motor. This will allow the implanting physician to visualize the inner radius. The placement guidewire must exit the outlet area on the inner radius of the cannula and align with the straight black line on the catheter. The physician can focus on advancing the placement guidewire and, if the cannula needs to be hyperextended, the scrub assistant is available to assist. 7.Make a transverse incision at the guidewire for the 21 Fr catheter. Use U-stitches (see Figure 5.14) instead of purse string sutures to avoid stenosis of the vessel after explantation. GP IIb-IIIa Inhibitors 8. Administer heparin and achieve ACT of at least 250 seconds. If the patient is receiving a GP IIb-IIIa inhibitor, the Impella® 5.0 Catheter can be inserted when ACT is 200 or above. 9. Insert the catheter into the vessel and advance along the 0.025 inch placement guidewire until resistance is met at the proximal vessel loop. 5.10 Instructions for Use & Clinical Reference Manual 11.Advance the repositioning sheath, located on the catheter shaft, through the incision and into the femoral artery until bleeding is controlled. Secure the sheath outside of the vessel using the supplied suture loop. To prevent device failure, do not start the Impella® 5.0 Catheter until the placement guidewire has been removed. Do NOT remove the Impella® 5.0 Catheter over the length of the placement guidewire. 12.Stabilize the guidewire and repositioning sheath and advance the catheter through the sheath. Follow the catheter under fluoroscopy as it is advanced across the aortic valve, positioning the inlet area of the catheter approximately 4 cm below the aortic valve annulus and in the middle of the ventricular chamber, free from the mitral valve chordae. Be careful not to coil the guidewire in the left ventricle. (Refer to Section 6 for information about console waveforms during placement.) 13.When the catheter is correctly positioned, slightly loosen the proximal vessel loop and remove the 0.025 inch guidewire. Leave at least 2 to 3 cm of the repositioning sheath inside the vessel. 14.Tighten the prepared U-stitches to seal the sheath. 15.Loosen the distal vessel loop. Then loosen the proximal vessel loop. Impella® 5.0 with the Impella® Console Do NOT Touch Inlet, Outlet, or Sensor Areas While feeding the Impella® 5.0 Catheter through the femoral artery, hold the catheter at the cannula or motor housing. Do NOT touch the inlet, outlet, or sensor areas. Maintaining ACT After insertion of the catheter (and until explant), ACT should be maintained at 160 to 180 seconds. 5.11 5 Using the Impella® 5.0 System 10.Loosen the proximal vessel loop and advance the catheter into the vessel. When the motor housing is entirely past the proximal vessel loop, temporarily tighten the loop to control bleeding.

Evaluate the catheter position in the aortic arch and remove any excess slack. The catheter should align against the lesser curvature of the aorta rather than the greater curvature. Verify placement with fluoroscopy and with the dual signal screen (see Figure 5.18). 6.Make sure there is no bleeding at the transition from the repositioning sheath to the femoral artery. Close and dress the wound. Secure the repositioning sheath by suturing it to the skin using the yellow eyelet on the sheath. 7.Attach the anticontamination sleeve to the sheath. Lock it in place by turning clockwise. Secure the catheter by tightening the connected anchoring ring. 8.Carefully extend the anticontamination sleeve to maximum length and secure the end closest to the red Impella® plug by tightening the anchoring ring. Vascular Closure When securing the repositioning sheath, vascular closure may be difficult in obese patients with extensive adipose tissue. 9.Reposition the catheter as necessary.

C onfirm that the console displays a pulsatile waveform and the inlet area of the Impella® 5.0 Catheter is approximately 4 cm below the aortic valve. Replacement Time If the purge flow is more than 7 mL/h or the dextrose concentration is less than 20%, replacement time will be less than 2 minutes. Replacement should always be performed as quickly as possible. Replacing the Purge Tubing When replacing the purge tubing, the replacement process must be completed within 2 minutes. The Impella® 5.0 Catheter may be damaged if replacement takes longer than 2 minutes. 1.Prepare a 20% dextrose solution with 50 IU heparin/mL. 2.Connect new purge tubing and CM-Set to the 20% dextrose solution. 3.Flush the purge tubing and CM-Set manually and close the roller clamp. 4.Press BOL on the infusion pump and enter a bolus release of 0.5–1 mL. Press OK to start the bolus. Multiple bolus releases may be required to reach 600 mmHg. 5.When the purge pressure on the Impella® Console reaches 600 mmHg, stop the bolus. 6.Press the red STOP key on the infusion pump to stop the infusion, then close the roller clamp. 7.Disconnect the current CM-Set from the catheter at the yellow check valve and from the gray pressure cable. 8.Open the door to the infusion pump and remove the current purge tubing. 9.Connect the new CM-Set to the catheter at the yellow check valve and to the gray pressure cable. Open the roller clamp. 10.Load the new purge tubing into the infusion pump. Close the infusion pump door. 11.Once the change out has occurred and the new purge tubing is threaded through the infusion pump, press VTBD to enter the new bag volume. 12.Press C on the keypad to clear the remaining volume and then enter the volume of the new bag. 13.Press OK to accept the new value. 14.Press the green Start button to start the infusion. 15.Press BOL on the infusion pump and enter a bolus release of 0.5–1 mL. Press OK to start the bolus to increase purge pressure back to the normal operating range. 16.If the purge pressure on the Impella® Console reaches 600 mmHg, press STOP on the infusion pump. Normal operating range is 300–700 mmHg. 5.14 Instructions for Use & Clinical Reference Manual Purge System Troubleshooting Low Purge Pressure If at any time during the course of support with the Impella® 5.0 Catheter, the Impella® Console alarms “Low Purge Pressure,” follow the instructions below. An Impella 5.0 Catheter in stable operation should never require an abrupt or significant increase in purge flow to maintain purge pressure. Stable operation is defined as operation in which the following criteria are met: ® Purge Pressure Range Purge pressure range: 300-700 mmHg • No leaks in any purge tubing connections • No recent changes in dextrose concentration • Constant performance level • Purge flow maintained with only small incremental changes in purge flow After confirming stable operation as defined above, if you observe a condition in which purge pressure drops and purge flow requires an abrupt or significant increase (eg, doubling the purge flow) to maintain purge pressure over 300 mmHg, this could be an indication of catheter damage. The steps that follow describe how to respond to the “Low Purge Pressure” alarm shown in Figure 5.19 if the criteria for stable operation listed above are met; however, the nature of the situation will determine the starting point for your response as shown in Table 5.1. Warning 0:06 Low Purge Pressure Increase Purge Rate! Check Purge System!

Heparin and Dextrose Infusion Rates 1. P ress BOL on the infusion pump and enter a bolus release of 0.5 mL. Press OK to start the bolus. The purge fluid contains heparin and dextrose. When changing the purge rate, carefully assess how the new heparin and dextrose infusion rates may affect the patient. For example, significantly increasing the purge rate may cause bleeding by increasing the amount of heparin delivered to the patient. As a result, the patient’s systemic heparin dose may need to be adjusted. 2. Inspect the purge system for leaks. Refer to Tables 5.2 and 5.3 for Abiomed-recommended dextrose and heparin concentrations in purge fluid. 3. P ress STOP if the Impella® Console shows purge pressure approximately 600 mmHg. Repeat Step 1 if necessary to reach 600 mmHg. If needed, increase infusion rate on the infusion pump until the purge pressure is maintained within the range of 300 to. 700 mmHg. 4. Switch to the 5 minute scale screen and monitor the purge pressure. 5. If the pressure remains stable, no other action is required. If the purge pressure is not stable and requires repeated boluses, proceed to Step 6. Figure 5.20 is an example of normal, stable behavior as displayed on the 5 minute . scale screen. • A single bolus is delivered to raise purge pressure to 600 mmHg. • Pressure is maintained above 300 mmHg. • Normal “settling” is shown after bolus.

If the low purge pressure alarms remain unresolved for more than 5 minutes, this may be a sign of catheter damage. Complete the following steps immediately: a.Change the catheter performance level to P1 by pressing the P-PERF button and the down arrow until P1 is displayed in the top left corner of the screen. Press OK button. b.Slowly pull back on the Impella® 5.0 Catheter until the catheter is in the descending aorta (approximately 20 cm for an average size patient; 1 cm marks are available . on the catheter). c.Turn off the Impella® 5.0 Catheter by pressing the P-PERF button and the down arrow until P0 is displayed in the top left corner of the console screen. Press OK button. dTurn off the Impella® Console and purge flow. e.Remove the Impella® 5.0 Catheter with the use of fluoroscopic imaging. If no fluoroscopy is available, leave the catheter in the descending aorta until fluoroscopy is available for visual assistance during removal of the catheter. Impella® 5.0 with the Impella® Console 5.17 High Purge Pressure High purge pressure alarms, if left unresolved, can deprive the Impella® 5.0 Catheter of the continuous flow of purge fluid needed to protect the motor. If blood enters the motor, the motor will have to work harder to maintain the set performance level. Motor current may increase gradually or sharply and the Impella® 5.0 Catheter may stop running. If the purge pressure exceeds 700 mmHg, the Impella® Console displays the alarm message shown in Figure 5.22. To resolve the high purge pressure alarm, perform the following steps. Warning 0:06 High Purge Pressure Unresolved High Purge Pressure Alarms Decrease Purge Rate! High purge pressure alarms that are not resolved by the recommendations provided could be an indication of a kink in the catheter located within the artery. In this case, the motor is no longer being purged and will eventually stop. Consider replacing the Impella® 5.0 Catheter. Check Purge System! Figure 5.22 High Purge Pressure Screen 1.Make sure that the clip on the pressure reservoir of the clear sidearm is not attached too close to the gray connector causing the purge line on the clear sidearm to kink.. If the clear sidearm is kinked, reposition the clip further down the connector cable away from the gray connector to remove the kink and allow purge fluid to flow freely. 2.Carefully inspect the purge tubing, clear sidearm, and entire visible length of the catheter for kinks, keeping in mind that kinks may be difficult to see and the purge lumen inside the clear sidearm may remain kinked after you “unkink” the clear sidearm. 3.If you do not detect any kinks, decrease the purge flow rate by 1 mL/h until the purge pressure is less than 700 mmHg. Do not decrease purge flow rate to less than 4 mL/h. 4.If purge pressure remains above 700 mmHg, decrease dextrose concentration to 5%. 5.18 Instructions for Use & Clinical Reference Manual Purge Pressure Management Strategies 5 Using the Impella® 5.0 System Figure 5.23 summarizes purge pressure management strategies. 20% Dextrose Solution with 50 Units Heparin/mL Purge flow rate 7 mL/h 300 mmHg Low Purge Pressure less than 300 mmHg Purge flow less than 20 mL/h 700 mmHg Purge Pressure between 300 and 700 mmHg Purge flow greater than 20 mL/h High Purge Pressure greater than 700 mmHg Purge flow between 4 mL/h and 20 mL/h 1.

Best practice, as determined by the medical community, should always be observed. In each case, the clinician must determine whether the application of information provided is appropriate for the particular clinical setting. General Patient Care Considerations • Do not raise the head of the bed to higher than a 30-degree angle. • Use knee immobilizer as needed to maintain access site straight. • Perform dressing changes per hospital protocol, using aseptic technique. • Assess access site for bleeding and hematoma. • Be careful not to pull on the Impella® 5.0 Catheter when transferring a patient from one bed to another. • To prevent purge line kinking, do not allow the red Impella® plug to hang freely from the catheter and do not bend the catheter near the red Impella® plug. Consider attaching the red Impella® plug and catheter to a short armboard to prevent the catheter from kinking near the plug. • Use care when moving or turning a patient; the Impella® 5.0 Catheter may move out of position and cause a positioning alarm. • Monitor pedal pulses. Impella® 5.0 with the Impella® Console 6.1 Battery Power Note If the Impella® Console is allowed to discharge completely and the system shuts down due to low battery, the console will need to charge for an extended period of time before the console will turn on again. Transport Within the Hospital Patients supported with the Impella® 5.0 System may require transport within the hospital for various reasons. Transport can be safe and simple for patients supported with Impella® 5.0 Catheter. Considerations for transport within the hospital: • The Impella® 5.0 System is designed to operate on battery power for at least 1 hour. • Confirm that the battery capacity displayed on the console is 100% and the battery capacity of the infusion pump is sufficient. • If transport time might be longer than 1 hour, bring an extension cord and confirm that you will be able to connect the console to AC power once you arrive at your destination. • Use care when rolling the Impella® 5.0 System cart, and pay close attention when going over thresholds and through elevator doors. • Do not stress the Impella® 5.0 Catheter cable from the console to the red Impella® plug. Right Heart Failure The Impella® 5.0 Catheter is a left-side support device only. Patients being supported by the Impella® 5.0 Catheter should be monitored for signs of right heart failure. Caregivers should monitor the patient closely for the following potential signs of right heart failure: • Reduced output from the Impella® 5.0 Catheter • Suction alarms • Elevated filling pressures (CVP) • Signs of liver failure • Elevated pulmonary pressures If the patient is exhibiting signs of right heart failure, the clinical team should assess the need for biventricular support. 6.2 Instructions for Use & Clinical Reference Manual ECG Interference 6 Patient Management Topics Operating the Impella® Console with the Impella® Power Supply may cause interference with electrocardiogram (ECG) signals. Check the electrode pads and leads for good fixation and contact. If interference persists, activate the 50/100 Hz band-elimination filter or the 60/120 Hz band-elimination filter (also known as notch filter) on your ECG device. The filter frequency will be based on the AC power frequency for the country in which you are operating the equipment. If your ECG device does not have the appropriate filters, disconnect the Impella® Power Supply temporarily from AC power to obtain an undisturbed signal. Carefully observe the battery status while running the Impella® Console on battery power. Latex The Impella® 5.0 Catheter and all accessories approved by Abiomed are 100% latex free. Positioning and Placement Devices High quality fluoroscopic imaging is the best method for determining catheter position and is required for Impella® 5.0 Catheter placement. If fluoroscopy is not readily available, transesophageal echocardiography (TEE) or transthoracic echocardiography (TTE) is appropriate for determining catheter position. (TEE and TTE are discussed next in this section.) Alternative methods for determining catheter position include portable C-Arm fluoroscopy and chest x-ray. Notes on Imaging: All imaging technology represents the anatomy in two dimensions (2D). It is not possible to assess the interactions between the Impella® 5.0 Catheter and the intraventricular anatomy that occur in three dimensions (3D). Abiomed strongly recommends that the Impella® 5.0 Catheter be repositioned, even if the imaging view shows correct position. Alternative imaging techniques, such as transesophageal echocardiography (TEE), can be useful to confirm the position of the Impella® 5.0 Catheter after placement. However, TEE is inadequate to reliably perform initial placement across the aortic valve. TEE does not allow visualization of the entire catheter assembly or guidewire. Impella® 5.0 with the Impella® Console Use Fluoroscopy for Placement Impella® 5.0 Catheter performance will be compromised if correct placement cannot be confirmed. While other imaging techniques, such as transesophageal echocardiography (TEE), can help confirm the position of the Impella® 5.0 Catheter after placement, TEE does not allow visualization of the entire catheter assembly or guidewire and is inadequate for reliably placing the Impella® 5.0 Catheter across the aortic valve. 6.3 Use of Echocardiography for Positioning of the Impella® 5.0 Catheter Background Echocardiography is a commonly used tool for evaluating the position of the Impella® 5.0 Catheter relative to the aortic valve and other intraventricular structures post-placement. The best echocardiographic views for positioning the Impella® 5.0 Catheter in the left ventricle are a long axis transesophageal echocardiogram (TEE) or a parasternal long axis transthoracic echocardiogram (TTE). These long axis views allow you to see both the aortic valve and Impella® 5.0 Catheter inlet area. Evaluate the position of the Impella® 5.0 Catheter if the Impella® Console displays position alarms or if you observe lower than expected flows or signs of hemolysis. If the catheter does not appear to be correctly positioned, initiate steps to reposition it. The illustrations on the following page identify the structures you would expect to see in transesophageal echocardiography (top) and transthoracic echocardiography (bottom). In these illustrations, the Impella® 5.0 Catheter is positioned correctly; however, these depictions are stylized and in actual echocardiograms the pigtail and inlet and outlet areas may not be seen as distinctly. 6.4 Instructions for Use & Clinical Reference Manual Patient Management Topics Impella® 5.0 Catheter outlet area LA Mitral valve 6 Transesophageal Echocardiogram (TEE) of Impella® Catheter Location of mitral chordae Aortic valve Papillary muscle RV LV Impella® 5.0 Catheter inlet area Transthoracic Echocardiogram (TTE) of Impella® Catheter Impella® 5.0 Catheter inlet area RV Septum Impella® 5.0 Catheter outlet area Papillary muscle Aorta LV LA Location of mitral chordae Mitral valve Figure 6.1 Labeled TEE and TTE Images of the Impella® 5.0 Catheter Position Impella® 5.0 with the Impella® Console 6.5 Four Impella® 5.0 Catheter positions you are likely to encounter when examining echocardiograms from patients supported with the Impella® 5.0 Catheter include: • Correct Impella® 5.0 Catheter position • Impella® 5.0 Catheter too far into the left ventricle • Impella® 5.0 Catheter inlet in the aorta • Impella® 5.0 Catheter in papillary muscle The following pages describe each situation. Figure 6.2 illustrates a transesophageal echocardiogram (TEE) of each situation. Figure 6.3 illustrates a transthoracic echocardiogram (TTE) of each. Correct Impella® 5.0 Catheter Position For optimal positioning of the Impella® 5.0 Catheter, the inlet area of the catheter should be about 4 cm below the aortic valve annulus and well away from papillary muscle and subannular structures. The outlet area should be well above the aortic valve. If the Impella® 5.0 Catheter is correctly positioned, echocardiography will likely show the following, as depicted in . Figures 6.2a (TEE) and 6.3a (TTE): • Catheter inlet area about 4 cm below the aortic valve • Catheter outlet area well above the aortic valve (frequently not visible on TEE or TTE images) • Catheter angled toward the left ventricular apex away from the heart wall and not curled up or blocking the mitral valve Impella® 5.0 Catheter Too Far into the Left Ventricle If the Impella® 5.0 Catheter is positioned too far into the left ventricle, the patient will not receive the benefit of Impella® 5.0 Catheter support. Blood will enter the inlet area and exit the outlet area within the ventricle. Obstruction of the Impella® 5.0 Catheter inlet area can lead to increased mechanical forces on blood cell walls and subsequent hemolysis, which often presents as dark or blood-colored urine. If the Impella® 5.0 Catheter is too far into the left ventricle, echocardiography will likely show the following, as depicted in Figures 6.2b (TEE) . and 6.3b (TTE): • Catheter inlet area more than 4 cm below the aortic valve • Catheter outlet area across or near the aortic valve • Catheter too close to the heart wall or mitral valve 6.6 Instructions for Use & Clinical Reference Manual Impella® 5.0 Catheter Inlet in the Aorta 6 Patient Management Topics If the inlet area of the Impella® 5.0 Catheter is in the aorta, the patient will not receive the benefit of Impella® 5.0 Catheter support. The catheter will pull blood from the aorta rather than the left ventricle. In addition, suction is possible if the inlet area is against the wall of the aorta or valve sinus. If the inlet area of the Impella® 5.0 Catheter is in the aorta, echocardiography will likely show the following, as depicted in Figures 6.2c (TEE) and 6.3c (TTE): • Catheter inlet area in aorta or near the aortic valve • Catheter pigtail too close to the mitral valve Impella® 5.0 Catheter in Papillary Muscle If the inlet area of the Impella® 5.0 Catheter is too close to or entangled in the papillary muscle and/or subannular structures surrounding the mitral valve, it can affect mitral valve function and negatively impact catheter flow. If the inlet area of the catheter is lodged adjacent to the papillary muscle, the inflow may be obstructed, resulting in suction alarms. This positioning is also likely to place the outlet area too close to the aortic valve, which can cause outflow at the level of the aortic valve with blood streaming back into the ventricle, resulting in turbulent flow and hemolysis. If the Impella® 5.0 Catheter is too close to or entangled in the papillary muscle, echocardiography will likely show the following, as depicted in Figures 6.2d (TEE) . and 6.3d (TTE): • Catheter pigtail in papillary muscle • Catheter inlet area more than 4 cm below the aortic valve or lodged between papillary muscle and the myocardial wall • Catheter outlet area too close to the aortic valve The following figures depict transesophageal and transthoracic echocardiographic images of these four Impella® 5.0 Catheter positions. Figure 6.2 shows four transesophageal depictions of Impella® 5.0 Catheter position and Figure 6.3 shows four transthoracic depictions of Impella® 5.0 Catheter position.

Adding color Doppler to an echo is another way to verify catheter position. If the Impella® 5.0 Catheter is correctly positioned, a dense mosaic pattern of turbulence will appear above the aortic valve near the outlet area of the catheter, as shown in the top image in Figure 6.4. If, however, the echocardiogram reveals a dense mosaic pattern of turbulence beneath the aortic valve (bottom image in Figure 6.4), this likely indicates that the outlet area of the catheter is in the wrong position, that is, the catheter is too far into the ventricle or entangled in papillary muscle. (Note: If using transesophageal echocardiography [TEE], look for the mosaic patterns in the same locations relative to the aortic valve and Impella® 5.0 Catheter outlet area.) Correct Impella® 5.0 Catheter Position (Color Doppler TTE) Incorrect Impella® 5.0 Catheter Position (Color Doppler TTE) Figure 6.4 Correct and Incorrect Impella® 5.0 Catheter Position (Color Doppler TTE) 6.10 Instructions for Use & Clinical Reference Manual Post-insertion Positioning (PIP) Checklist 6 Patient Management Topics Completing the steps shown in the following post-insertion positioning checklist can help to ensure proper position of the Impella® 5.0 Catheter following insertion. Pay particular attention to positioning after the patient is moved from the operating room or catheterization laboratory. 1.Remove slack in the Impella® 5.0 Catheter by increasing performance level to P9 and align the catheter against the lesser curvature of the aorta (rather than the greater curvature). 2.Use fluoroscopy to verify that the slack has been removed. 3.Verify that the Impella® 5.0 Catheter inlet area is optimally positioned about 4 cm below the aortic valve. 4.Return to previous performance level. 5.Secure the Impella® 5.0 Catheter at a firm external fixation point in the groin area. Understanding and Managing Impella® 5.0 Catheter Position Alarms The Impella® Console continuously monitors the Impella® 5.0 Catheter based on the placement signal and the motor current. • Placement Signal: Is the signal pulsatile or flattened? • Motor Current: Is the signal pulsatile or flattened? If the system alarms with one of the positioning alarms described in this section, fluoroscopic imaging is the best method for confirming position. You can also use TEE, TTE, or a standard chest X-ray. Placement Monitoring If the Impella 5.0 Catheter is either partly (just the pigtail) or completely in the ventricle, reposition the catheter under imaging guidance. If guidance is not available, use the repositioning guide to reestablish proper placement. ® If the Impella® 5.0 Catheter is completely out of the ventricle, do not attempt to reposition the catheter across the valve without a guidewire. The tables on the following pages describe possible placement conditions and the expected alarm messages, associated signal characteristics, and placement monitoring icons. Impella® 5.0 with the Impella® Console The placement monitoring screen will display “Disabled Due to Low Performance Level” if catheter performance level is less than P1. If there is a problem with the pressure sensor, it will display “Disabled Due to Non Reliable Sensor.” 6.11 Correct Impella® 5.0 Catheter Position If the Impella® 5.0 Catheter is in the correct position, the placement signal, motor current, dual signal, and placement monitoring screens will appear as shown in Figure 6.5.

The repositioning menu can also be used as a guide for correcting Impella® 5.0 Catheter positioning. 2.Confirm that the placement signal and motor current are both pulsatile. Impella® 5.0 with the Impella® Console 6.13 Low Native Heart Pulsatility When a patient has poor native ventricular function, the placement signal may remain pulsatile; however, the amplitude will be dampened and both the minimum and maximum values will be greater than zero because the aortic valve does not open and the Impella® 5.0 Catheter raises the aortic blood pressure above the ventricular pressure during systole. In a situation of low native heart pulsatility, the Impella® Console may not be able to determine the catheter position and the placement signal, motor current, dual signal, and placement monitoring screens will appear as shown in Figure 6.7.

Figure 6.8 Impella® 5.0 Catheter Outlet Area on or near Aortic Valve Actions to take: 1.Assess and adjust Impella® 5.0 Catheter position under fluoroscopic or echocardiographic guidance, if available. 2.If fluoroscopic or echocardiographic guidance is not available, reduce the performance level to P2 and gently pull the catheter back 1 cm and see if the condition resolves. Impella® 5.0 with the Impella® Console 6.15 Suction Suction may occur if the blood volume available for the Impella® 5.0 Catheter is inadequate or restricted. Suction limits the amount of support that the Impella® 5.0 Catheter can provide to the patient and results in a decrease in arterial pressure and cardiac output. It can damage blood cells, leading to hemolysis. It may also be an indicator of right heart failure. If a suction alarm occurs, follow the recommended actions in the alarm display by decreasing the performance. 1.Check the catheter for correct positioning using imaging. Reposition the catheter by rotating or moving it into or out of the ventricle slightly. Either or both of these actions could help move the inlet of the catheter away from the interior ventricular wall. 2.Assess patient’s fluid intake and output to confirm adequate volume status. 3.Confirm right ventricular function by assessing CVP or right side function on echo. If CVP is not an option, check the pulmonary artery diastolic pressure to assess the patient volume status. 4. Return performance level to pre-alarm setting. Hemolysis When blood is pumped, it is subjected to mechanical forces. Depending on the strength of the blood cells and the amount of force applied, the cells may be damaged, allowing hemoglobin to enter the plasma. Pumping forces can be generated by a variety of medical procedures including heart lung bypass, hemodialysis, or ventricular assist device (VAD) support. Patient conditions— including catheter position, pre-existing medical conditions, and small left ventricular volumes— may also play a role in patient susceptibility to hemolysis. Patients who develop high levels of hemolysis may show signs of decreased hemoglobin levels, dark or blood-colored urine, and in some cases, acute renal failure. Plasma-free hemoglobin (PfHgb) is the best indicator to confirm whether a patient is exposed to an unacceptable level of hemolysis. Management technique may differ depending on the underlying cause of hemolysis. Table 6.1 provides guidance for various circumstances. 6.16 Instructions for Use & Clinical Reference Manual Table 6.1 Guide for Managing Hemolysis in Various Circumstances 6 Console Indicators Clinical Indicators Management Impella 5.0 inlet area in close proximity to intraventricular wall • Suction alarms • Lower than expected flows Imaging (see note) • Reposition the Impella® 5.0 Catheter by rotating or moving the catheter into or out of the ventricle slightly. Either or both of these actions could help move the inlet of the catheter away from the intraventricular wall. • If reposition will be delayed, reduce the flow by 1 or 2 performance levels if tolerated by patient hemodynamics. Return performance level after repositioning. • Reassess position after performance level has returned to desired target value. Wrong catheter position • Position alarms with higher Imaging (see note) than expected flows • Suction alarms with lower than expected flows • Pump outlet blocked alarms • Reposition the Impella® 5.0 Catheter by rotating or moving the catheter into or out of the ventricle slightly. Either or both of these actions could help move the inlet of the catheter away from the intraventricular wall. • If reposition will be delayed, reduce the flow by 1 or 2 performance levels if tolerated by patient hemodynamics. Return performance level after repositioning. • Reassess position after performance level has returned to desired target value. Higher than needed flow setting • There may be no console indicators • Suction alarms • Normal hemodynamics • Native recovery • Reduce performance level until patient pressure starts to drop. • Increase performance by 1 level. Inadequate filling volume • Position alarms • Suction alarms • Lower than expected flows • Low CVP • Low PCWP • Low AOP • High PA pressures • Right heart failure • High urine output • Increased bleeding or chest tube drainage • Reduce the flow by 1 or 2 performance levels if tolerated by patient hemodynamics. • Correct I and O balance. • Consider giving volume; additional volume will expand the end systolic ventricular volume. • Reduce PA pressure. • Improve right heart function. Pre-existing patient conditions or other medical procedures N/A • Patient past medical history • Current procedures or treatments ® Note on imaging: All imaging technology represents the anatomy in two dimensions (2D). It is not possible to assess the interactions between the Impella® 5.0 Catheter and the intraventricular anatomy that occur in three dimensions (3D). Abiomed strongly recommends that the Impella® 5.0 Catheter be repositioned, even if the imaging view shows correct position. Impella® 5.0 with the Impella® Console 6.17 Patient Management Topics Condition Accuracy of Displayed Flow Rate Pressure Sensor Drift and Sensor Failure The performance level of the Impella® 5.0 Catheter is automatically set to P2 during zeroing if the catheter is operating above P0. Performance level remains at P2 after zeroing and does not automatically return to its prior setting. Under normal operating conditions, displayed flow rate can deviate from the actual flow rate by up to 0.5 L/min. Sensor Drift and Effects on Flow Zeroing and Sensor Drift Only zero the sensor when you observe evidence of sensor drift. Abiomed does NOT recommend zeroing the differential pressure sensor when there is NO evidence of sensor drift because the performance level is reduced to P2 during zeroing. The electrical signal produced by the differential pressure sensor may drift over time. This drifting is normal behavior and is characterized by an upward or downward shift in the placement signal along the y-axis of the console display; however, the amplitude (peak-to-trough, or maximum to minimum) of the waveform will not change. When sensor drifting occurs, it affects the Impella® 5.0 Catheter flow calculations and the displayed flow rate will not match the expected flow. (Refer to Table 6.2 to see what the expected flow rates for each performance level should be.) Table 6.2 Expected Flow Rate Displayed on Console Performance Level Flow rate (L/min) P1 0.0 – 1.4 P2 0.5 – 2.6 P3 0.5 – 3.1 P4 0.9 – 3.4 P5 1.4 – 3.7 P6 1.8 – 4.0 P7 2.6 – 4.4 P8 3.4 – 4.7 P9 4.2 – 5.3 If you observe that the placement waveform has shifted up or down on the y-axis, or the expected flow does not match the current performance level setting, zero the differential pressure sensor by performing the following steps: 1.Press the SIGNAL key until the placement signal is displayed. 2.Press the ZERO key. “Placement Signal Offset Adjust” is displayed. 3.Press OK within 10 seconds to start the zeroing algorithm. The Console will display the “Calculation is Running” message. Resetting Performance Level After zeroing, return the performance level to the level at which it was set prior to zeroing. 6.18 4.Press OK to accept the new setting when the console displays the “Placement Signal Offset Adjust finished!” message. 5.The Impella® 5.0 Catheter continues running at performance level P2 and the lower value of the differential pressure signal should display about 0±6 mmHg. 6.If the adjusted value deviates from zero by more than 6 mmHg, repeat the zeroing procedure (steps 2-4). 7.If the adjusted value is 0±6 mmHg, slowly increase the performance level, step by step, until you reach the setting used before the zeroing procedure. Instructions for Use & Clinical Reference Manual Sensor Failure and Effects on Flow Calculations 6 Patient Management Topics If the pressure sensor fails, the console can no longer calculate the flow rate. The console will display the flow as “?.?”. Sensor Failure and Effects on Position Control If the pressure sensor fails, placement monitoring is switched off because it is not possible to display a precise position for the catheter. In this case, the motor current signal or imaging procedures can be used for position control. As long as the motor current signal is pulsatile, . the Impella® 5.0 Catheter is correctly positioned across the valve. This signal must be monitored closely because the catheter can become dislodged (displaced) when moving the patient or changing the patient’s position. Therefore, if patient hemodynamics change—for example, if arterial pressure falls or there are signs of left ventricular failure—check the correct positioning of the catheter using imaging procedures (eg, TEE) and the motor current signal. Suction Detection During Sensor Drift or Sensor Failure If sensor drift occurs or the pressure sensor fails, the console can no longer detect suction. . (For more information about suction, refer to the “Suction” discussion earlier in this section of the manual.) The effectiveness of Impella® 5.0 Catheter support can only be assessed by monitoring patient hemodynamics, cardiac imaging, and the Impella® 5.0 Catheter motor current. Signs of suction include: • A drop in the patient’s arterial pressure • Decreased output, if a cardiac monitor is in place • Decreased motor current If imaging reveals that the suction is caused by the Impella® 5.0 Catheter inlet area in close proximity to the ventricular wall, reposition the catheter as described in Table 6.1. If hemodynamic parameters, such as low aortic pressure or high pulmonary artery pressure, indicate suction caused by inadequate filling volume, reduce flow and follow the management strategies described in Table 6.1. Impella® 5.0 with the Impella® Console 6.19 Operating the Impella® 5.0 Catheter Without Heparin in the Purge Solution The Impella® 5.0 Catheter is designed to be operated with a purge solution that contains heparin. Operation of the system without heparin in the purge solution has not been tested. In the event that a patient is intolerant to heparin, due to heparin-induced thrombocytopenia (HIT) or bleeding, physicians should use their clinical judgment in assessing the risks versus benefits of operating the Impella® 5.0 System without heparin. If it is in the best interest of the patient to operate the system without heparin, the dextrose solution is still required, and physicians should consider an alternative anticoagulant delivered systemically. Do NOT add any alternative anticoagulant (such as a direct thrombin inhibitor) to the purge solution. The Impella® 5.0 Catheter has not been tested with any alternative anticoagulants present in the purge solution. How to Change to A Backup Console A backup Impella® Console should be available at all times when a patient is on support. In the event of a console failure, follow the steps below to transition the Impella® 5.0 System to the backup console. 1.Confirm that the backup console is powered on and ready. 2.Transfer the pressure transducer cable from the original console to the pressure connector socket (yellow) on the left side of the backup console. 3.Remove the blue connector cable from the original console and plug it into the catheter connector socket (blue) located on the right side of the backup console. 4.Once the Impella® 5.0 Catheter is connected to the backup console, the “Quick Start” message will appear on the screen asking you to confirm restarting the Impella® 5.0 Catheter at the previously set performance (P) level. 5.Press OK within 10 seconds to confirm restarting the Impella® 5.0 Catheter at the previously set performance level. 6.20 Instructions for Use & Clinical Reference Manual 7 Impella® Console Alarms and Warnings Impella® 5.0 Console Alarms................................................................. 7.1 Handling Alarms and Warnings......................................................................... 7.1 Impella® 5.0 Console Warnings............................................................7.3 Impella® 5.0 Console Alarms 7 Impella® Console Alarms and Warnings Handling Alarms and Warnings You can mute alarms and warnings by pressing the OK button once.
