Abstract: The present disclosure is directed towards a socket and suspension system that offers the user increased ease of donning the prosthesis, volume adjustability, and improved circulation. The prosthetic includes a socket and liner. The socket and liner can be custom made for the amputee or prefabricated. The liner acts as an interface between the custom socket and the amputee's residual limb. Moving fluid in or out of the area between the liner and the socket causes the liner to push away from the socket wall or pull into the socket wall thereby changing the volume inside the socket. Moving the liner closer to the socket wall enlarges the volume inside the socket making it easier for the patient to put on the prosthetic. The socket and suspension system can include a pump which can manually or automatically adjust the volume inside the socket and suspension of the prosthesis.

Abstract: An auto-adjusting prosthetic ankle apparatus includes a base portion that is pivotally fixed to an attachment portion. The base portion is structured for being fixed to a foot blade, while the attachment portion is structured for fixing the prosthetic ankle apparatus to a lower leg portion of a prosthetic limb. The prosthetic ankle includes a computer controllable damping mechanism that is functionally and mechanically coupled between the base portion and the attachment portion. The damping mechanism enables a damping level to be selectively applied to lightly damp or heavily damp a relative motion between the base portion and the attachment portion as a user is walking to provide an auto-adjusting of the prosthetic ankle to changes in a ground surface being traversed and during various stages of a walking cycle.
