Abstract

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. A sealed cavity is formed between the socket and the residual limb. The wearer may use a liner over the residual limb for comfort. A vacuum source is connected to a vacuum valve 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. A liner for a hypobarically-controlled socket for an artificial limb, with a liner interface bonding the liner to the socket and forming a seal between the liner and the socket. The liner may be permanently attached to the socket or the liner may be removed from the socket for replacement.

         11 . The liner of  claim 8 , wherein the liner interface comprises two adhering surfaces, a first surface that bonds to the liner and a second surface that bonds to the socket.  
     
     
         12 . The liner of  claim 11 , wherein the liner interface comprises a double sided adhesive layer.  
     
     
         13 . The liner of  claim 8 , wherein the liner interface comprises hook and loop material.  
     
     
         14 . The liner of  claim 8 , wherein the liner interface comprises magnetic material, such that magnetic material on the socket is attractable to magnetic material of the liner.  
     
     
         15 . An artificial limb for an amputee, the artificial limb comprising a socket configured to removably receive a residual limb of an amputee, the residual limb received within a liner, and a liner interface for removably bonding the liner and the socket.  
     
     
         16 . The artificial limb of  claim 15 , wherein the liner interface is configured to substantially seal the liner to the socket to minimize air leakage into space between the liner and socket.  
     
     
         17 . The artificial limb of  claim 15 , wherein the liner interface comprises at least one adhering surface that bonds to one of the liner and socket.  
     
     
         18 . The artificial limb of  claim 15 , wherein the liner interface comprises two adhering surfaces, a first surface that bonds to the liner and a second surface that bonds to the socket.  
     
     
         19 . The artificial limb of  claim 18 , wherein the liner interface comprises a double sided adhesive layer.
