Abstract

The present invention provides, in various embodiments, a breast implant with an RFID transponder embedded therein, so that the implant can be conveniently identified while inside the human body, and methods of making the same.

Claims

1. A method of manufacturing a breast implant having a transponder disposed therein, comprising:

placing a mold into a silicone material one or more times to form a shell comprising one or more silicone layers;

removing the mold from the shell, wherein the shell has an opening where the mold was removed;

covering the opening with a patch;

after covering the opening, placing the transponder radially inward of the shell through a hole in the patch;

filling the shell with a silicone gel through the hole in the patch such that the transponder is disposed within the silicone gel; and

curing the silicone gel, wherein the transponder is disposed within the cured silicone gel radially inward of the patch.

2. The method of claim 1, wherein the transponder is flexibly fixed within the cured silicone gel adjacent to the patch.

3. The method of claim 1, further comprising sterilizing the breast implant at a temperature ranging from about 120°

C. to about 150°

C. for up to about 36 hours.

4. The method of claim 1, further comprising applying a vacuum to the silicone gel-filled shell before curing the silicone gel.

5. The method of claim 1, wherein curing the silicone gel comprises heating the silicone gel with the transponder therein at a temperature ranging from about 140°

C. to about 200°

C.

6. A method of manufacturing a breast implant, the method comprising:

preparing a silicone shell defining a cavity, the shell including an aperture;

covering the aperture with a patch;

introducing a silicone gel into the cavity;

introducing a transponder into the cavity, wherein the transponder is movable within the silicone gel relative to the shell, while being in proximity of the patch; and

curing the silicone gel with the transponder disposed therein to fix a position of the transponder within the silicone gel.

7. The method of claim 6, further comprising removing air from the silicone gel inside the cavity before curing the silicone gel.

8. The method of claim 6, wherein the transponder is flexibly fixed within the cured silicone gel adjacent to the patch.

9. The method of claim 6, wherein the transponder is configured to withstand temperatures up to 210°

C. during curing of the silicone gel.

10. The method of claim 6, wherein curing the silicone gel comprises heating the silicone gel with the transponder disposed therein at a temperature ranging from about 140°

C. to about 200°

C. for up to about 8 hours.

11. The method of claim 6, wherein introducing the silicone gel into the cavity comprises injecting the silicone gel into the cavity through a hole in the patch.

12. The method of claim 6, wherein the transponder is glass encapsulated.

13. A method of manufacturing a breast implant, the method comprising:

preparing a silicone shell defining a cavity, the shell including a hole;

placing a transponder into the cavity;

covering the hole with a patch;

filling the shell with a silicone gel, wherein the transponder is movable within the silicone gel relative to the shell, while being in proximity of the patch;

and

curing the silicone gel to fix a position of the transponder in the silicone gel.

14. The method of claim 13, wherein the silicone gel is cured at a temperature ranging from about 140°

C. to about 200°

C.

15. The method of claim 13, wherein the transponder is disposed within the cured silicone gel adjacent to the patch.

16. The method of claim 13, wherein the transponder is a high temperature-stable radio-frequency transponder.
