The unique Helix design also helps lower extremity amputees start their steps more smoothly, improves toe clearance, and makes it easier to extend the leg during walking. Users will spend much less energy thinking about their next step, walk more naturally and confidently, and experience less pain in the back and joints. Click Here for More Information.

Silicone Prosthesis

ARTech Silicone Prostheses: ARTech fabricates custom hand, partial hand, and finger prostheses to fit any type, age, and color. Acrylic fingernails are painted to closely match the patients’ residual fingers, and silicone-based paint is used to simulate hair, wrinkles, or any other type of markings to blend with the residual hand. Without close examination, ARTech’s natural looking restorations are virtually undetectable. ARTech silicone prostheses are also functional. They can improve the gait and posture, ease lower back pain, relieve pressure on bone spurs and other sensitive areas, protect the tissue from further injury, improve the operation of myoelectric hands, etc. When a restoration has a natural appearance, sculpted and painted to match the opposite limb, as opposed to the robotic or mannequin look of traditional prostheses, utilization by the patient is maximized. This enhanced usability may well be one of the most important functions of all. Click Here for More Information.

Socket Design

RevoFit Socket Design: Revofit technology features a micro-adjustable prosthetic limb that allows the amputee to instantly control the fit of the socket without ever having to remove it. Based on the Boa technology that is used to adjust and tighten ski boots, Revofit allows the user to easily and quickly adjust the fit of the socket with an easy click-by-click turn of the dial, whether it’s tightening it up for a more secure fit or decreasing tension when driving, sitting or resting. The Revofit is designed with custom “floating” panels, targeting the specific areas of the limb that fluctuate in volume, while leaving the sensitive areas undisturbed. Precision placement of these adjustable panels allows them to flow with your changing body and your changing needs. The panels are lined with custom pads for soft, smooth compression and exceptional comfort. Click Here for More Information.
