Pro-Flex^® XC

HC040194

Pro-Flex XC has been developed to comfortably accommodate the relatively active user, who enjoys hiking and jogging, as well as levelground walking. Comes with an aesthetically pleasing, anatomical footcover and integrated male pyramid.

Unity for Pro-Flex XC is available either pre-fit with a new foot or as a retrofit option. Used in combination with Iceross® Seal-In® liners, Unity provides advanced vacuum suspension for the socket during ambulation, without the constraints of an external sleeve. It adds minimal weight to the existing prosthesis and its simple mechanical design means there are no batteries to worry about. Reliable, effective and easy to use, it is designed to improve balance and prevent skin problems.

Impact Levels

	Impact Level	Example
	Low Daily activities involving gentle, steady walking with the use of a walking aid. Example: Moving around at home, modest walking in the community.
	Moderate Daily activities involving average walking with the ability to vary speed or walking pattern. Example: Going to the shops, confident outdoor walking.
	High Daily activities involving fast walking, jogging and climbing stairs. Example: Heavy-lifting, manual labor, recreational sports.

Pro-Flex® XC Features

Active Tibial Progression

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.

Benefit: More natural gait and reduced walking effort.

CARBON-X® Active Heel

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.

Benefit: Reducing impact to the joints and residual limb thus increases comfort, reduces joint and limb damage.

Full Length Toe Lever

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.

Benefit: Improved walking symmetry and reduced impact to the sound limb.

Proportional Response

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

Benefit: Customized construction optimizes walking efficiency thus reducing fatigue for the user.

Sandal Toe

Sandal toe foot designs incorporate a split between the first and second toe.

Benefit: More anatomical look for increased visual appeal and more functional compatibility with sandal shoes.

Split Toe

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

Benefit: Helps to maintain balance, stability and reduces peak impact during loading.

Unity® - Sleeveless Vacuum Suspension

Unity offers the security and freedom of vacuum suspension, but without the sensation and restrictions of a sleeve. This advanced system from Össur effectively addresses volume fluctuation and is totally compatible with Flex-Foot technology.

Key advantages

No sleeve required: Greater mobility and user acceptance
15-22 in Hg Vacuum: Effective volume stabilization
Simple design: Quick and easy to achieve/release vacuum
Independent pump: Foot function uncompromised
Light weight: Complete system weighs only 130g

Unity for all

With the Unity Vacuum System by Össur, there is finally an elevated vacuum system for all users. Whether an above-knee or below-knee, low active or high active, mechanical or microprocessor solution is required, the Unity Vacuum System offers the flexibility to combine a variety of Össur feet and knees to achieve the optimal combination of equipment for each unique user.

Unity is only recommended with sleeveless Seal-In technology
