Appl. No.:

10/266394

Inventors:

Jeremy Adelson - Bainbridge Island WA, US

International Classification:

A61F005/00

US Classification:

Abstract:

A knee brace for coupling to a patient's knee. The knee brace can include a flexion/extension joint, a first arm coupled to the flexion/extension joint, and a first ramp positioned to engage the first arm. The first ramp can be shaped to move the first arm towards the patient's leg as the patient's knee extends and away from the patient's leg as the patient's knee flexes. Alternatively, the first ramp can be shaped to move the first arm away from the patient's leg as the patient's knee extends and toward the patient's leg as the patient's knee flexes.

Abstract:

A prosthetic walking system including a pylon, a prosthetic ankle, and a prosthetic foot, any two or more of which can be integrally connected into a single, continuous unit. The prosthetic ankle can be a rearwardly-facing, generally C-shaped member, and may include an upper leg, an interconnecting portion, and a lower leg. The prosthetic ankle may include a weakened portion so that the prosthetic walking system is better adapted to flex at the prosthetic ankle rather than at the pylon. A link or link assembly can be coupled to at least one of the pylon and the upper leg of the prosthetic ankle and to at least one of the lower leg of the prosthetic ankle and the prosthetic foot in order to limit the displacement between the upper leg and the lower leg of the prosthetic ankle.
