Abstract
A socket assembly for use with a prosthetic device. The socket assembly receives at least a portion of a residual limb on which the prosthetic device is attached. The socket assembly includes an airtight outer shell adapted and constructed to receive a portion of the residual limb of an amputee, the shell having an interior and an exterior. A vacuum-permeable skin interface is secured to at least a portion of the interior of the outer shell. A high-vacuum valve communicates between the interior of the socket and the exterior of the socket, the valve being adapted and constructed to be attached to a vacuum source. When the residual limb is positioned in the socket assembly and the high-vacuum valve is connected to a vacuum source, the vacuum force exerted by the source is evenly distributed to the residual limb through the skin interface.
