Application:
These instructions are for use by the practitioner.
The EchelonVAC foot is to be used exclusively as part of a lower limb prosthesis.
The EchelonVAC 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. A moderate energy return foot with multi-axial ankle
movement. Independent heel and toe springs provides some axial deflection. The split toe
provides good ground compliance.

Description and Purpose
This device is recommended for users that have the potential to achieve Activity Level 3 who may
benefit from enhanced stability and an increase in confidence on uneven surfaces.
Of course there are exceptions and in our recommendation we want to allow for unique,
individual circumstances. There may also be a number of users in the Activity Levels 2 and 4* who
would benefit from the enhanced stability offered by the EchelonVAC, but this decision should
be made with sound and thorough justification.
*(maximum user weight 100kg (220lbs) and always use one higher spring rate category than
shown in the Spring Set Selection table).
Contra-indications:
This device may not be suitable for Activity Level 1 individuals or for competitive sports events,
as these types of users will be better served by a specially designed prosthesis optimized for their
needs.
It may not be suitable for use on individuals with poor balance , especially for bilateral use. If
the user has any pertinent circulation condition seek medical advice if there is a possible risk of
adverse reactions.
It is NOT recommended for use for:
• Wearers with poor cognitive function
• Users on dialysis
• Users with neuromas preventing weight bearing
• Use where a large range of heel height is required without re-alignment
EchelonVAC should only be fitted by suitably trained practitioners and should only be used with
suitable, well fitting total contact sockets. There should be no reliefs or voids into which tissue
may be drawn by the vacuum.
• If multiple walled sockets are used there should be no voids in their construction
• There should be no excessive flares to socket brim or trim lines
Intended for single user.
Ensure that the user has understood all instructions for use, drawing particular attention to the
section regarding Maintenance.
In addition to the visco-elastic, self-aligning hydraulic ankle it generates an elevated vacuum in
the range 12-17in Hg.
