Patent ID: 8784708

Claim:
A method of producing a custom-fitted prosthetic socket device for a residual limb, the method comprising: covering at least the distal end region of the residual limb with a residual limb liner; positioning the covered distal end region of the residual limb at least partially within a socket cup, so that a spaced relationship between the exterior surface of the limb liner and the interior surface of the socket cup is maintained, the socket cup being fabricated from a rigid material and having a floor and a wall, a top edge of the wall forming an opening at a top end of the socket cup; introducing an expandable, hardenable filler material into the socket cup; expanding the filler material to fill the volume between the exterior surface of the limb liner and the interior surface of the socket cup; hardening the expanded filler material to a hardened condition; and removing the socket cup, the hardened filler material, and the limb liner, from the residual limb.
