Abstract
An elevated vacuum locking system for prosthetic limb. An exemplary embodiment may include a plunger pin mounted to a flexible liner and including a through passage between a location proximate the exterior of the liner and a distal end of the plunger pin; a locking mechanism mounted within the distal end of a socket; a manifold mounted to the exterior of the distal end of the socket and including a cavity adapted to receive the distal end of the plunger pin when the patient's residual limb and the liner are installed into the socket, the manifold including a through passage connecting an interior of the cavity to an exterior fitting; and a vacuum pump operative to withdraw air from the interior of the socket via the through passage of the plunger pin, the cavity, and the through passage of the manifold.
