4 Function

The device is a complete external transfemoral
limb prosthesis, which utilizes sensors and
actuators controlled via microprocessors in
an integrated hydro-pneumatic knee and
hydraulic foot system.
The Linx app-based interface programs
the device to the individual user's gait
characteristics during the Calibration stages
of the set-up sequence. This set-up can then
be fine-tuned to meet specific requirements.
Alternatively, programming can be achieved
via the buttons at the rear of the knee, but
with less fine tuning options than are available
with the app.
The limb provides control of the stance and
swing phase of the user's gait while the stance
control is optimized to provide secure support
during ambulation on all terrains.
The enhanced stability of the system offers a
Standing Mode with control of knee flexion
and ankle for standing.
There is increased ground contact and better
resistance to knee flexion during ramp
descent. There is an optimized assistance for
ramp ascent provided by the limb.
It has a dynamic action during stair descent
with an easy start of knee flexion coupled
with increasing support to gently lower the
user during flexion. It also provides supportive
resistance to flexion as soon as the knee stops
flexing and increased supportive resistance
to flexion to prevent 'stumbles' associated
with instability at heel strike. Heel rise during
walking is actively controlled via hydraulic
damping.
The device is powered by a rechargeable
lithium-ion battery pack, charged via a
magnetically secured and self-aligning charger
connection on the posterior of the knee.
