Abstract:
1. A tubular prosthetic liner having an open proximal end and a closed-end distal area, and interior and exterior surfaces, the liner forming a cavity delimited by the interior surface, the liner adapted to envelop a residual limb, the liner comprising: a fabric layer defining first and second surfaces, the first fabric layer surface continuously defining the exterior surface of the liner; at least one elastomeric polymeric layer having first and second surfaces, the at least one elastomeric polymeric layer surface bonded to the second surface of the fabric layer; and a seam formed by opposed sides of the fabric layer joined together, the opposed sides of the fabric layer forming an excess portion directed toward the cavity of the liner and embedded in the at least one elastomeric polymeric layer, wherein the opposed sides of the fabric layer are joined together by a welding element, the welding element is a polymeric film contiguously and integrally joined along the opposed sides of the fabric layer.
