Abstract

A passive transponder may be encoded with a number or code of up to 64 binary bits and then associated with or mounted to virtually any living tissue implant for implantation in a human. 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 progress and use for medical as well as legal reasons.

Claims

1. A method for rendering identifiable a transplant member comprised at least in part of living tissue, said method comprising the steps of:

encoding a transponder with information concerning said transplant member, and

contemporaneously transplanting said transplant member and implanting said transponder in a human,

said transponder being encoded in a manner so that such information may be readily retrieved with a procedure which is noninvasive to the human.

2. The method of claim 1 further comprising the step of physically securing said transponder to said transplant member so that said transplant member and transponder are implanted together and in physical proximity with each other.

3. The method of claim 1 wherein the step of physically securing includes affixing the transponder to the transplant member.

4. The method of claim 1 further comprising mounting the transponder within the profile of the transplant member.

5. The method of claim 1 wherein the transplant member is totally comprised of living tissue.

6. The method of claim 1 wherein the step of encoding said transponder comprises the step of encoding said transponder in a manner to enable the transponder to be read electromagnetically with the implant.

7. A method for rendering identifiable a transplant member in a human, the method comprising the steps of:

encoding a transponder with information concerning a transplant member comprised at least in part of living tissue, and

transplanting said transplant member and implanting said transponder in a human,

said transponder being encoded in a manner so that such information may be readily retrieved with a procedure which is noninvasive to the human.

8. The method of claim 7 wherein the step of transplanting said transplant member and implanting said transponder in a human comprises contemporaneously transplanting said transplant member and implanting said transponder in a human.

9. The method of claim 7 further comprising the step of mounting the transponder within the profile of the transplant member.

10. The method of claim 7 wherein the step encoding a transponder with information concerning a transplant member comprised at least in part of living tissue comprises the step of encoding the transponder with information concerning a transplant member totally comprised of living tissue.

11. The method of claim 7 wherein said transponder is encoded in a manner to be read electromagnetically.
