Abstract: A breast implant includes a shell fashioned from one of a group of materials which exhibit radiolucency at those x-ray in- tensities normally encountered for mammographic procedures. The radiolucent shell may be filled with radiolucent fill material as previously taught to thereby comprise a fully radiolucent breast implant. The radiolucent breast implant enhances the use of mammography in detecting tumors in patients having breast implants to more effectively diagnose and treat cancer.

Abstract: A filler material for a surgically implantable prosthesis comprised of a synthetic triglyceride having a viscosity substantially greater than that of naturally occurring triglycerides is provided. The triglyceride composition is formed of saturated alkyl chains to reduce or limit the potential for oxidation of the alkyl chains to form peroxide groups which adversely affect the biocompatibility of the filler material and the implant. Preferably, the filler material has a viscosity substantially the equivalent of a normal human breast. The synthetic triglyceride filler material may also have a lower viscosity which is a liquid at room temperature for use in inflatable devices. Prostheses containing filler material having the desired viscosity and antioxidation characteristics are also provided as well as a method for preparing the filler material.

Abstract: A method for forming an open cell texturized surface in a silicone elastomer layer of a breast implant, or other medical implant, is created by forming a layer of uncured silicone elastomer, applying a coating of particles to the surface thereof, and curing the layer by heating it at an elevated temperature which also volatilizes the particles such that their constituent gases boil through the surface of the layer and create the texturing.

Abstract: A passive transponder may be encoded with a number or code of up to 64 binary bits and then mounted to virtually any prosthesis implanted in a human, such as a breast implant. After implantation, the transponder's code may be conveniently read with a hand held electromagnetic reader which may merely be brought within proximity of the transponder. The encoded transponder may thus be read in a non-invasive procedure and without the use of any sophisticated or potentially harmful medical equipment or technology such as X-ray. The information encoded in the transponder may correspond to patient demographics and implant data to aid in tracking the implant's manufacturer and use for medical as well as legal reasons.
