Flex-Foot® Assure

Flex-Foot® Assure


HC050031

The Flex-Foot Assure is ideal as a first prosthesis or a more permanent option for the less active, particularly those experiencing poor vascular health and/or diabetes.

Designed specifically for slower speed walkers, Flex-Foot Assure incorporates an active heel combined with the full-length keel that work together to protect the vulnerable sound limb. The proven design and simple fit of Assure allows basic ambulators to take advantage of premium technology just right for them.

Flex-Foot® Assure Features

Active Tibial Progression

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

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

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

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.


Waterproof

Waterproof

The use of first-rate material such as carbon fiber, titanium and high-grade aluminum provides permanent protection against harmful ingress of water. Even after submersion in water, the foot’s structural parts maintain their integrity and continue to provide full support, function and durability.

Benefit: No loss of prosthetic function under wet circumstances.


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
