  • Patent number: 7316795
    Abstract: The invention relates to method for overmolding a painted silicone prosthesis of a human extremity. A silicone prosthesis is first molded from a solid replica of a human extremity and then painted to closely resemble the color of the recipient person. An elasotmeric polymer material having the properties of elasticity, transparency, and non-adhesiveness to cured silicone rubber is applied to the replica to form a transparent glove-like overmold. The glove has an inner surface that is mirrored by the surface of the replica. The distal portion of the glove-like overmold is partially filled with a predetermined amount of viscous uncured silicone liquid and the painted silicone prosthesis is then inserted into the glove which is stretched tightly over the prosthesis. A compressive force is externally applied in a radial compressive and proximate direction to uniformly distribute the liquid silicone over the painted surface of the prosthesis.
