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. In an implant adapted for implantation in a human, said implant being comprised at least in part of living tissue, the improvement comprising a transponder associated with said implant so that said transponder is implantable as said implant is implanted, said transponder having means for being encoded with a unique tag so that said transponder may be readily identified after implantation by reading said unique tag.

2. The implant of claim 1 wherein said transponder has means for its tag to be read with a non-invasive protocol.

3. The implant of claim 2 wherein said transponder has means for its tag to be read electromagnetically.

4. The implant of claim 3 wherein said transponder has means for being energized by a remote reader thereby obviating a need for a battery to be contained in said transponder.

5. The implant of claim 4 wherein said transponder has means for being encoded with a number selected from within a range of 0 to 64 bits, binary.

6. The implant of claim 1 wherein said transponder is mounted within the profile of said implant.

7. The implant of claim 1 wherein said prosthesis a totally living tissue implant.

8. An implant intended for human implantation, said implant being comprised at least in part of living tissue and including a transponder associated therewith so that said transponder is implantable as said implant is implanted, said transponder having means for being encoded with a unique identifier so that said transponder'"'"'s identifier may be read after implantation and associated with a data base for reporting selected data corresponding to said implant.

9. The implant of claim 8 wherein said transponder has means for its identifier to be read remotely.

10. The implant of claim 9 wherein said transponder has means for its identifier to be read electromagnetically.

11. The implant of claim 10 wherein said transponder has means for being energized by a remote reader thereby obviating a need for a battery to be contained in said transponder.

12. The implant of claim 11 wherein said transponder has means for being encoded with a number selected from within the range of 0 to 64 bits, binary.

13. The implant of claims 8 wherein said transponder is mounted within the profile of said implant.

14. The implant of claim 8 wherein said prosthesis is a totally living tissue implant.
