A hypobarically-controlled artificial limb for amputees includes a single socket with a volume and shape to receive a substantial portion of the residual limb (14). A liner (92) with a volume less than the residual limb (14) is donned over ,the residual limb, with the liner (92) tensioned into a total contact relationship with the residual limb (14). A sealed cavity is formed between the socket, (60) and the liner (92). A vacuum source (70) is connected to the socket cavity (62) thereby drawing the residual limb (14) a nd liner (92) into firm and total contact with the socket (60). To compensate f or some air leakage past the, seal (140), there is a mechanism to maintain the vacuum in the cavity.
