A hypobarically-controlled artificial limb for amputees includes an outer socket, a flexible, compressible inner socket within the outer socket with a cavity for receiving the residual limb, a space between the inner socket and the outer socket, a vacuum source connected to the cavity, a positive pressure source connected to the space, a regulator for controlling the vacuum source and positive pressure source, and a seal for making an airtight seal between the residual limb and the socket. Another embodiment includes a semi-compressible molding material in the space to mold to the contours of the residual limb under the influence of vacuum and/or positive pressure.

[ What is claimed:] [1.] A hypobarically-controlled artificial limb for amputees who have a residual limb, the artificial limb comprising:(a) an outer socket with a volume and shape to receive a substantial portion of the residual limb with a space therebetween;(b) an inner socket with a cavity having a volume and shape for receiving a substantial portion of the residual limb and fitting in said space between said outer socket and the residual limb, said inner socket having an inner surface and an outer surface, said inner surface adapted to receive and support the residual limb, said outer surface opposing said outer socket;(c) a vacuum source; and(d) a vacuum valve connected to said vacuum source and in flow communication with said cavity to thereby facilitate drawing of the residual limb into firm contact with said inner surface of said inner socket.
