1 Description and Intended Purpose

These instructions are for use by the practitioner.
The term device is used throughout this document to refer to EchelonVAC .
Application:
The 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. 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.
In addition to the visco-elastic, self-aligning hydraulic ankle it generates an elevated vacuum in
the range 12-17in Hg.

Activity Level

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 device, but this decision should be
made with sound and thorough justification.
*(maximum user weight 100 kg (220 lb) and always use one higher spring rate category than
shown in the Spring Set Selection table).
Activity Level 3
Has the ability or potential for ambulation with variable cadence.
Typical of the community ambulator who has the ability to traverse most environmental
barriers and may have vocational, therapeutic, or exercise activity that demands prosthetic
utilization beyond simple locomotion.

Clinical Benefits

• Increased ground clearance reduces risk of trips and falls
• Improved balance through self-alignment
• Improved ground compliance for slope negotiation
• Healthier residual limb tissue and skin
• Reduction in residual limb volume fluctuations
• Reduced loading on the residual limb
• Improved kinetic gait symmetry
• Improved wound management
• Decreased pistoning
• Increased walking speed
