ABSTRACT:
A liner for use with a prosthesis comprises an inner layer, a cushion layer, an outer layer, and a bead defining the upper edge of the liner. The bead can be disposed between the inner and outer layers and may comprise an elastomeric material of non-uniform thickness. A method for making a prosthesis liner comprises a) making a positive of the residual limb, b) constructing an inner layer on the outer surface of the positive, c) defining an upper edge of the liner, d) forming a mold that reflects the shape of the positive and the defined upper edge, e) using the mold to shape a cushion layer that has a defined upper edge, f) applying a bead along the desired upper edge of the liner, g) applying the cushion layer to the inner layer; and h) constructing an outer layer on the outer surface of the cushion layer.
