A hypobarically-controlled artificial limb (50) for amputees includes a single socket (60) with a volume and shape to receive a substantial portion of the residual limb. A seal (84) between the socket and the residual limb. A sealed cavity is formed between the socket and the residual limb. Optionally, the wearer may use a liner (92) over the residual limb for comfort. A vacuum source (70) is connected to a vacuum valve (78) connected to the cavity to suspend the artificial limb from the residual limb and to control and minimize volumetric and fluid changes within the residual limb. |
