1 Description and Intended Purpose
Please keep these instructions.
The term device is used throughout this document to refer to EchelonVT .
Application
This device is to be used exclusively as part of a lower limb prosthesis.
Intended for single user.
The device provides limited self-alignment of the prosthesis on varied terrain and following
footwear changes. It is intended to improve on postural sway and symmetry while easing
abnormal pressures at the socket interface.
The device also includes a spring element capable of absorbing axial and rotational shocks
intended to reduce shear stresses at the residuum/socket interface.
2 Safety Information
This warning symbol highlights important safety information which must be
followed carefully.
Any changes in the performance or
function of the limb e.g. restricted
movement, non-smooth motion or
unusual noises should be immediately
reported to your service provider.
Always use a hand rail when descending
stairs and at any other time if available.
The device is not suitable for extreme
sports, running or cycle racing, ice and
snow sports, extreme slopes and steps.
Any such activities undertaken are done
so completely at the users’ own risk.
Recreational cycling is acceptable.
Assembly, maintenance and repair of
the device must only be carried out by
a suitably qualied clinician.
The user should contact their clinician if
their condition changes.
Ensure only suitably retrotted vehicles
are used when driving. All persons are
required to observe their respective
driving laws when operating motor
vehicles.
To minimise the risk of slipping and
tripping, appropriate footwear that
ts securely onto the footshell must be
used at all times.
After continuous use the ankle casing
may become hot to the touch.
Avoid exposure to extreme heat and/
or cold.
The user must not adjust or tamper
with the setup of the device.
Be aware of nger trap hazard at all
times.

6 Limitations on Use
Intended life:
A local risk assessment should be carried out based upon activity and usage.
Lifting loads:
User weight and activity is governed by the stated limits.
Load carrying by the user should be based on a local risk assessment.
Environment
Avoid exposing the device to corrosive elements such
as water, acids and other liquids. Also avoid abrasive
environments such as those containing sand for example as
these may promote premature wear.
Exclusively for use between -15˚C and 50˚C (5˚F to 122˚F).
Maintenance must be carried out by competent personnel.
We recommend a regular visual check at least annually. Signs of wear that may aect function
should be reported to their service provider (e.g. signicant wear or excessive discoloration from
long term exposure to UV).
Any changes in performance of this device must be reported to the practitioner.
Changes in performance may include:
• Increase in ankle stiness
• Changes in axial or torsional stiness
• Reduced ankle support (free movement)
• Softening of springs
• Excessive play in bearings
• Any unusual noise
The practitioner must also be informed of any changes in body weight and/or activity level.
Cleaning
Use a damp cloth and mild soap to clean outside surfaces. Do not use aggressive cleansers.
The device comprises a hydraulic body assembly containing adjustable hydraulic valves.
The valves can be independently adjusted to increase and reduce hydraulic resistance to
plantarexion and dorsiexion.
The proximal part of the hydraulic body assembly contains a spring component that allows
the pyramid tube to deect and/or rotate through a limited range under an axial and/or
torsional load. When the load is removed the spring returns to its original position. The eect
of this movement is to attenuate any shock forces that would otherwise be transmitted to the
residuum/socket interface both in axial and rotational directions.
The hydraulic body assembly is connected to a carrier assembly via two pivot pins. Heel and toe
springs are attached to the carrier using titanium and stainless steel screws. The foot is wrapped
in a UHM PE sock which is in turn surrounded by a PU foot shell.
