Apparatus and methods for improved prosthesis donning, doffing, retention, and fit. A valve located in a prosthetic socket port includes a body, a core, a spring located partially within the core, a diaphragm, and a maintained operator. The operator includes a recess and a protrusion. The operator may be indexed to a displacement or vent position. When the operator is indexed to the displacement position, a tip of the core is pressed against the recess via the spring, and the diaphragm displaces any air that enters into the prosthetic socket when a load is applied to the residual limb. When the operator is laterally actuated, it is indexed to the vent position and the core tip moves from the recess to the protrusion. In this position, the diaphragm opens the socket cavity to the external atmosphere via valve vents, thereby facilitating prosthesis donning and doffing.

Prosthetic valve

A method of manufacturing a prosthetic socket having an access port that employs a housing with a cylindrical extension. The method includes the step of molding a shell over a socket model and a mold dummy to form an intermediate port. The method additionally includes the step of trimming the intermediate port along a trim line passing through a cavity defined by the mold dummy to create a circular opening in the shell. The mold dummy has a first diameter generally conforming to a diameter of the cylindrical extension of the housing. The method further includes the steps of passing the cylindrical extension through the opening and securing the access port to the shell.
