Vari-Flex XC with Evo

Vari-Flex XC with Evo

by Ossur

The Vari-Flex XC combines superb dynamics and comfort for a range of activities.

The Vari-Flex XC with EVO is provides impact reduction and smooth roll-over which is designed to accommodate hiking and jogging, as well as level ground walking.

The EVO technology ensures fluid, natural gait with a smooth roll-over motion. A more natural gait reduces fatigue and puts less strain on the lower back and sound side.

Features:

  • Vertical forces generated at heel contact are stored and translated into a linear motion described as Active Tibial Progression. This action reduces the need to actively push the body forward using the contralateral foot and also equalizes stride length.

  • The Carbon-X Active Heel stores the energy during loading response as the amputee transfers his or her body weight onto the prosthetic foot. Energy is gradually released from the heel providing optimal return for forward progression of the limb.

  • The EVO (Energy Vector Optimization) feature is generated by controlling how the ground reaction force is transferred to the prosthetic foot. Each step is optimized through the magnitude, placement and direction of forces for maximum efficiency. EVO enables the amputee to develop the most natural gait progression possible which reduces fatigue and puts less pressure on the sound side.

  • The full length keel/toe lever matches the length of the sound foot, providing improved support to the prosthetic limb during late stance. It ensures that users spend equal time on the prosthetic foot and natural limb, thus providing improved walking dynamics and reduced impact to the sound limb.

  • The layering of carbon fibre, optimised through extensive computer analysis and mechanical testing, ensures that the deflection of the carbon fibre heel and forefoot components are proportional to the user’s weight and impact level.

  • A split toe feature allows the foot to adjust to uneven surfaces, allowing amputees to walk with stability and comfort on uneven ground.

  • The vertical shock pylon reduces impact to the residual limb, joints and lower back during daily activities. It also ensures a more energy-efficient gait by minimising vertical displacement of the centre of gravity.
