Abstract:
1. A prosthetic component comprising: a layer of durable fabric of a shape having a proximal open end for introduction of a residual leg and a closed distal end for covering a distal end of said residual leg, said fabric of sufficient length to rise from said distal end of a residual leg over an entire portion of said residual leg to be covered by a prosthetic socket; and a block copolymer and plasticizing oil cushioning gel layer secured to only an inside surface of said fabric such that said gel layer is in direct contact with a residual leg and cushions said residual leg inside a prosthetic socket when said prosthetic component is worn by an amputee, said gel absent from an outer surface of said fabric such that said prosthetic component may readily slide into and out of a prosthetic socket without said gel sticking thereto and such that said prosthetic component may be rolled during donning or doffing thereof without said gel causing said prosthetic component to stick to itself; wherein said fabric and gel are of sufficient thickness to stand alone as a sole interface between a residual leg and a prosthetic socket; and wherein said prosthetic component has sufficient flexibility and elasticity to substantially conform to the shape of a residual leg to which it is donned while being sufficiently tight to substantially eliminate air pockets between said residual leg and said gel layer.
