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.

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.

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).

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.

When the Impella® 5.0 Catheter is not properly placed across the aortic valve, or when it is fully
in the aorta or fully in the ventricle, the pressures outside and inside the cannula are the same
throughout the cardiac cycle. 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).

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.

5 Using the Impella® 5.0 System
Refer to the instructions for use supplied with the infusion pump being used
before using the infusion pump with the Impella® 5.0 System.
Preparing the Impella® 5.0 System
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.
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 remove the Impella® 5.0 Catheter over the length of the placement
guidewire.
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.
Do NOT kink or clamp any part of the Impella® 5.0 Catheter.
Protect the Clear
Sidearm and Catheter
The clear sidearm of the
Impella® 5.0 Catheter
between the pressure
reservoir and red Impella®
plug can become kinked.
Support the pressure reservoir
and the length of the catheter
as you remove the Impella®
5.0 Catheter from the tray.
Avoid allowing the pressure
reservoir to hang freely from
the red Impella® plug and
avoid bending the catheter
near the red Impella® plug.
Sensitive Medical Device
The Impella® 5.0 Catheter is a
sensitive medical device with
extremely fine tolerances. In
particular, the inlet and outlet
areas of the catheter assembly
may be damaged if subjected
to strong external forces.
5.4
Connecting the Impella® 5.0 Catheter and Connector Cable
1. S lowly open the package and carefully remove the Impella® 5.0 Catheter using sterile
technique. Inspect the catheter, including its connector, for damage.
2.Remove the connector cable from its package using sterile technique. Inspect the cable
for damage, including damage to the connector pins at the console end.
3.Secure the black end of the cable to the sterile field.
4. Insert the catheter plug into the connector cable socket (black end). The tab and the
slot must be aligned during connection (see Figure 5.5).

become kinked and fluid will
not flow freely.
During the procedure, check
the clip regularly to make
sure it remains correctly
positioned, especially after
changing the purge tubing.
Console Color Coding
The connectors on the
Impella® Console are
color-coded. The pressure
connector socket on the left
side of the console has yellow
markings that match the
yellow plug on the end of the

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).

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.

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.

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.

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.

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%.

Patient Weaning
Weaning the patient from the Impella® 5.0 Catheter is at the discretion of the physician.
The following weaning protocols are provided as guidance only.
Rapid Weaning
1. Initiate rapid weaning by decreasing catheter performance level in 2-level steps at
intervals of several minutes (for example, P6 to P4 to P2). Do NOT decrease the
performance level to below P2 until just before removing the catheter from the
ventricle.
5.20
Instructions for Use & Clinical Reference Manual
3. If the patient’s hemodynamics remain stable, decrease the performance level to P1,
pull the catheter into the aorta, and stop the motor by decreasing the performance
level to P0.
4. Explant the catheter.
5.Follow institutional guidelines for arterial closure.
6.Disconnect the connector cable from the Impella® Console and the catheter by
sliding back the locking sleeves (at the <= => markings) and removing the plugs .
(see Figure 5.25). Do NOT twist the plugs because the contact pins may
be damaged.

7.Press MENU. Select “Switch Off Console” and press OK.
Remove the Impella® 5.0
Catheter With Care
Slow Weaning
1.Initiate slow weaning by decreasing catheter performance level in 2-level steps over
time as cardiac function allows (for example, P6 to P4 to P2). Do NOT decrease
the performance level to below P2 until just before removing the catheter from the
ventricle.
Removal of the Impella® 5.0
Catheter must be completed
with care to avoid damage to
the catheter assembly.
2.When the performance level has been reduced to P2, maintain the patient on P2
support until the patient’s hemodynamics remain stable before discontinuing circulatory
support.
3.If the patient’s hemodynamics remain stable, decrease the performance level to P1,
pull the catheter into the aorta, and stop the motor by decreasing the performance level
to P0.
4.Explant the catheter.
5.Follow institutional guidelines for arterial closure.
6.Disconnect the connector cable from the Impella® Console and the catheter by

Patient Management Topics
The information and instructions in this section of the manual are not intended to supersede
established medical procedures concerning patient care. 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.

Placement
Impella® 5.0 Catheter
performance will be
compromised if correct
placement cannot be
confirmed. While other
imaging techniques,
such as transesophageal

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.

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

Color Doppler Echocardiography
When moving a patient supported with an Impella® 5.0 Catheter, it is important to monitor
catheter migration. 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.)

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.

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.

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.

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

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.

After zeroing, return the
performance level to the level

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.

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.

Anatomic Considerations
In a small number of cases (about 2 in every 100 patients) the Impella® 5.0 Catheter cannot
be successfully placed; or can be placed, and the performance is compromised due to patients
having anatomic conditions outside of the range for which the Impella® 5.0 Catheter was
designed.
The following table describes anatomic conditions that may affect the insertion or operation of
the Impella® 5.0 Catheter. Physicians should consider these characteristics when evaluating small
or very tall patients for Impella® 5.0 Catheter support.
Condition
Effect
The size and tortuosity of the
femoral and iliac arteries
Limits the ability of the Impella® 5.0 Catheter to be advanced
from the insertion site into the left ventricle
Distance from the insertion site
to the apex of the left ventricle
For very tall patients, the maximum interventional length may
not be sufficient to allow correct placement of the Impella® 5.0
Catheter
Systolic left ventricular (LV) long The Impella® 5.0 Catheter may interfere with the mitral valve
axis < 7 cm
Systolic left ventricular (LV) long The Impella® 5.0 Catheter pigtail will not have a surface to push
axis > 11 cm
against to help stabilize its position, and may have a tendency to
swing or bounce
Cleaning
• Clean the Impella® Console, the pump test plug, and the cables by wiping them down
with disinfectant.
• Do not allow any fluids to enter the connector sockets.
8.6
Instructions for Use & Clinical Reference Manual
• Place the Impella® Console on a horizontal surface to prevent falling.
• Connect the AC power cable from the Impella® Power Supply to an AC outlet.
• The battery may be destroyed if the Impella® Console is stored with a depleted battery.
