ABSTRACT:
A prosthetic socket is fitted at a distance from its distal end with an annular chamber. This annular chamber is closed by a contour-conforming sealing wall facing the inner side of the prosthetic socket, said wall being designed to hermetically rest against the outer side of a residual limb. The space between the contour-conforming wall and the hard prosthetic socket is vented to atmosphere, whereby self-enhancing compression by the sealing wall against a residual limb arises when a partial vacuum arises in the distal prosthetic socket between the wall and the distal end. A liner having a sealing wall also is disclosed.
