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 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.
