1 Description and purpose
The Elan is a biomimetic foot and ankle system with microprocessor controlled dorsiflexion
and plantar flexion. It is designed to adapt dynamically (via motorized valves) to provide
assistance when walking on a variety of surfaces, when changing gait speeds and increased
levels of safety and security when walking and standing.
Application
• These instructions are for use by the practitioner
• The Elan is to be used exclusively as part of a lower limb prosthesis
• Intended for single user
Ensure that the user has understood all instructions for use, drawing particular attention to
the sections regarding maintenance and use of the battery charger connection.
Features
(See also Section 3 Function)
• Dynamic damping resistance aims to improve gait characteristics enabling safer walking
• Microprocessor control of resistance in real time
• The Elan Software adapts to individual user gait characteristics
• Standing Support mode
• Aims to reduce stress at the socket interface
• PC interface setup with Bluetooth® link and direct communications
• Power is supplied via an integral rechargeable battery pack
This device provides limited self-alignment of the prosthesis on varied terrain and following
footwear changes. It is intended to improve postural sway, balance stability and inter-limb
loading symmetry while easing high pressures at the socket interface.
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.
There are exceptions and in our recommendation we want to allow for unique, individual
circumstances. There may also be a number of users of Activity Levels 2 and 4* who would
benefit from the enhanced stability offered by the Elan.
Users at Activity Levels 2 and 4* will require softer or stiffer springs as appropriate for the
individual user rather than as shown in the spring selection guide.
*(maximum user weight 100 kg (220 lbs) 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.
