UNITY
®
Sleeveless Vacuum
THE ONLY ADVANCED VACUUM SYSTEM DESIGNED FOR USE
WITH PROVEN SEAL-IN® AND FLEX-FOOT® TECHNOLOGY.
SLEEVELESS VACUUM WITH SEAL-IN® V
The Unity® Vacuum System by Össur elevates vacuum within the
socket without the use of a suspension sleeve. This innovative
solution eases knee flexion while increasing available range of
motion and comfort. Designed specifically for elevated vacuum
application, the Seal-In V liner with dual sealing membrane provides
a secure seal inside the socket. The internal seal eliminates risk of
punctures and leaks typically encountered with conventional sleevedependent vacuum systems. Soft and compliant silicone
construction provides close fit distally, even pressure distribution
and superior cushioning properties. By applying vacuum to the
distal soft tissues, volume stability is maintained where it is needed
the most throughout the day. With two different seal heights
available, Seal-In V optimises elevated vacuum for a variety of limb
lengths.
LIGHT WEIGHT AND EFFICIENT WITH FLEX-FOOT® PERFORMANCE
By harnessing deflection of the Carbon-X® Active Heel, the Unity
vacuum pump draws air out of the socket and elevates vacuum
up to 22inHG within a few steps. Adding only 130g to the overall
weight of the foot module, the Unity vacuum pump is a light
weight solution. Directly attached to the foot module, the pump
is discreetly housed within the foot shell and does not add bulk or
detract from the cosmetic appearance of the prosthesis. Because
the vacuum pump is not dependent upon any additional shock
or rotation elements, the Unity system is easily incorporated into
a variety of Flex-Foot models. A wide range of dynamic Flex-Foot
solutions are available with the Unity Vacuum System to meet all
lifestyle and activity requirements.
Unity is currently available with: PROPRIO FOOT®,
LP Vari-Flex®, Vari-Flex®, LP Rotate™, Re-Flex Rotate™
and Re-Flex Shock™

Effective volume stabilisation
Specially designed for elevated vacuum application, the
Seal-In V incorporates a dual-sealing membrane and volume
adaptive blades. Two sealing membranes provide enhanced
security to prevent leaks. If volume changes, the volume
adaptive blades consistently press the seal against the
socket wall and prevent the seal from folding.

PARTICULAR CATEGORY?
UNITY® FOR PROPRIO FOOT
Adaptive prosthetic device for
low to moderately active belowknee amputees that mimics
natural foot motion
Iceross Seal-In V Standard
Seal-In V is available with the seal at two different heights.
The High Profile variant should be used for longer limb
lengths.
The Seal-In V is composed of DermoGel® silicone which
provides the best distal compliance and cushioning available
from Össur. The Wave feature enhances the elasticity of the
liner to provide easier and greater knee flexion. Active Skin
care ingredients and the Silken Inner Surface nourish and
protect the skin.

CAN I STILL USE WEDGES

STIFFNESS?
Yes, it is still possible to
use the heel wedges. They
are inserted into the heel
and do not interfere with
the heel pad or pump
mechanism.
UNITY®
Sleeveless Vacuum
The Unity system has a tri-function valve which enables an effective vacuum to be achieved easily, quickly and
automatically, within a few gentle steps. Equally important to the user is the release function – just press the button and
the vacuum is released instantly.
EXPULSION
lets air through easily
when donning the socket
VACUUM BYPASS
lets air into the vacuum
pump via a check valve,
so the socket is still
airtight in the unlikely
event of tube failure
FRAME & SUPPORT BLADE
The support blade is attached to the foot (proximally) while
the frame sits in the heel pad. The two are fixed to each
other where they meet, close to the middle of the foot.
The frame and support blade are designed in a way that
when weight is placed on the heel of the prosthetic foot
the frame moves upward and the support blade moves
downwards, thus pulling and expanding the membrane
between them.
CHECK VALVES
When air is efficiently drawn out from the socket at each
step, the check valves ensure that the air does not flow
back into the socket.
HEEL PAD
The heel pad acts as a secure support for Unity’s upper
blade, and as a bumper (stop) for heel displacement at
high load.
MEMBRANE
The membrane pump mechanism is located between the
two blades. When the membrane expands, air is efficiently
drawn out of the socket.
RELEASE BUTTON
lets in air, so the vacuum
is easily released for

The evolution of Unity
We hear the same thing from a lot of customers whose patients want the security and freedom of vacuum
suspension, but without the sensation and restrictions of a sleeve. They want a system that can address volume
fluctuations and they also want a system that’s compatible with Flex-Foot® technology.
We didn’t want to compromise the function of our Flex-Foot shock units, so we designed a pump that would
operate independently, one that required minimal loading to achieve a powerful vacuum. With Unity, the pump is
operated using a fraction of the energy harvested by the heel of the foot.
So, we began to explore how we could build on the Iceross Seal-In® V, already a successful suspension liner in its
own right. The integrated seal provides a natural boundary for distal vacuum and it is there, at the distal end, where
the soft tissues are least stable.
The whole system weighs only 130g. When you combine that factor with better socket fit and the dynamics of a FlexFoot, you get a very light and responsive feel, something that’s been borne out by our user testing and feedback.

For extra convenience and system compatibilit y, the Unit y T T Valve Kit is highly recommended as a means of connec ting to the socket.
