Temporary implant with transponder and methods for locating and indentifying

摘要

A passive transponder may be encoded with a binary number or code of 64 bits or more and then associated with or mounted to virtually any implant intended for implantation in a human including temporary implants such as drug release implants and organ displacement devices. 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-rays. Where the position of the implant in the human changes over time, or is otherwise unknown to attending medical personnel, the transponder and implant can be located by using a strength of signal indicator on the electromagnetic reader. The information encoded in the transponder may simply be a tag for locating the implant, or may correspond to patient demographics and implant data to aid in tracking the implant and patient for medical as well as legal reasons.
