Abstract: A temporarily implantable organ displacement implant is comprised of a bladder with a one-way valve for being filled with a fluid for displacement of a healthy organ from a tissue site desired to be irradiated by radiation therapy. This organ displacement implant is substantially radiolucent which thereby facilitates its placement and minimizes its interference with the radiation therapy.

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.

Abstract: A biosensing transponder for implantation in an organism including a human comprises a biosensor for sensing one or more physical properties related to the organism after the device has been implanted, including optical, mechanical, chemical, and electrochemical properties, and a transponder for wirelessly transmitting data corresponding to the sensed parameter value to a remote reader. Disclosed embodiments utilize temperature sensors, strain sensors, pressure sensors, magnetic sensors, acceleration sensors, ionizing radiation sensors, acoustic wave sensors, chemical sensors including direct chemical sensors and dye based chemical sensors, and photosensors including imagers and integrated spectrophotometers. The transponder includes an energy coupler for wirelessly energizing the device with a remote energy source, and a control circuit for controlling and accessing the biosensor and for storing identifying data. The energy coupler can be an inductive circuit for coupling electromagnetic energy, a photoelectric transducer for coupling optical energy, or a piezoelectric transducer for coupling ultrasonic energy. The control circuit can be configured to delay, either randomly or by a fixed period of time, transmission of data indicative of the sensed parameter value to thereby prevent a data collision with an adjacent like device. Methods for using an implantable biosensing transponder include the steps of associating the device with an implant, including temporary implants, prostheses, and living tissue implants, physically attaching the device to a flexible catheter, sensing parameter values in an organism, and transmitting data corresponding to the sensed parameter values to a remote reader.

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 (28) 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 (24) which may merely be brought within proximity of the transponder (28). The encoded transponder (28) 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 (28) 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.
