Abstract
A multi-axis prosthetic ankle for connection of a prosthetic lower leg to a prosthetic foot. In one embodiment, a prosthetic foot connection component is connected to a prosthetic lower leg connection component only by means of an elastomeric material, thereby allowing for multi-axis movement of the ankle without requiring direct contact between the two components. In other embodiments of the ankle, a prosthetic foot connection component may be mechanically connected to a prosthetic lower leg connection component. However, the design of the mechanical connection and the use of an elastomeric material casing allows for movement of the ankle without surface-to-surface sliding contact between the two components. Compression of the elastomeric material, as well as one or more mechanical stops may be used to control and limit movement of the ankle.
