Abstract

Claims (59)

1. An implantable medical device comprising:

a shell defining a cavity, the shell including one or more layers;

wherein the one or more layers includes an electroconductive layer; and

a transponder enclosed within the electroconductive layer, the transponder including:

a capsule having a cavity;

an enameled wire having a first end and a second end; and

an integrated circuit chip coupled to each of the first end and the second end;

wherein the capsule configured to house the enameled wire and the integrated circuit chip;

wherein the capsule includes an adhesive material filling at least 30 percent of the cavity.

2. The implantable medical device of claim 1 , wherein the one or more layers includes an inner layer and an outer layer.

3. The implantable medical device of claim 2 , wherein the electroconductive layer is positioned between the inner layer and the outer layer;

wherein the one or more layers includes an inner layer and an outer layer formed from a non-electroconductive material.

4. The implantable medical device of claim 1 , wherein the transponder is configured to transmit radio frequency wave transmissions, the radio frequency wave transmissions between 100 kHz and 3 GHz.

5. The implantable medical device of claim 1 , including a sensor;

wherein the electroconductive layer is configured to interfere with transmission of a signal from the transponder or the sensor through the shell.

6. The implantable medical device of claim 1 , wherein the transponder includes a capsule enclosing the enameled wire and the integrated circuit chip.

7. An implantable medical device comprising:

a multilayered shell defining a cavity, the multilayered shell including:

an outer layer; and

an electroconductive layer;

an integrated port assembly coupled with a surface of the multilayered shell, the integrated port assembly including:

a chamber; and

a self-sealing port dome covering an opening of the chamber; and

a transponder positioned within the implantable medical device, the transponder including:

a non-ferromagnetic enameled wire.

8. The implantable medical device of claim 7 , wherein the transponder is positioned within the integrated port assembly.

9. The implantable medical device of claim 7 , wherein the multilayered shell includes an inner layer, and the electroconductive layer is positioned between the outer layer and the inner layer;

wherein the transponder is enclosed in the electroconductive layer.

10. The implantable medical device of claim 7 , wherein the electroconductive layer is a mesh layer;

wherein the electroconductive layer is configured to prevent a signal from being received by the transponder or a signal being transmitted from the transponder.

11. The implantable medical device of claim 7 , including:

a capsule defining a cavity; and

an integrated circuit chip in communication with the non-ferromagnetic enameled wire;

wherein the non-ferromagnetic wire and the integrated circuit chip are positioned within the cavity.

12. The implantable medical device of claim 11 , wherein the non-ferromagnetic enameled wire is formed in a coil having a first end and a second end;

wherein the integrated circuit chip is coupled with one or more of the first end or the second end of the coil.

13. A system for monitoring a status of an implantable medical device, the system including:

a multilayered shell defining a cavity, the multilayered shell including:

an outer layer;

an electroconductive layer; and

an integrated port assembly positioned on the multilayered shell, the integrated port assembly including:

an integrated port dome configured to fit against a wall of the multilayered shell; and

a valve assembly interconnected with the integrated port dome; and

a transponder positioned within the implantable medical device, the transponder including:

a non-ferromagnetic enameled wire; and

an external communication device configured to communicate with the transponder, the external communication device including:

a microcontroller; and

one or more antenna.

14. The system for monitoring the status of claim 13 , including an inner layer;

wherein the electroconductive layer is positioned between the outer layer and the inner layer;

wherein the transponder is enclosed by the electroconductive layer.

15. The system for monitoring the status of claim 13 , wherein the external communication device is configured to receive a stronger signal from the transponder when the electroconductive layer or the multilayered shell is breached than when the electroconductive layer or the multilayered shell is intact.

16. The system for monitoring the status of claim 13 , wherein the non-ferromagnetic enameled wire is formed in a coil, the coil having a first end and a second end, the transponder including:

a capsule enclosing the coil; and

an integrated circuit chip coupled to the first end and the second end;

wherein the external communication device is configured to send signals to the transponder and receive signals from the transponder.

17. The system for monitoring the status of claim 13 , including:

at least one sensor disposed in the multilayered shell, the at least one sensor configured to detect or measure one or more of biological, chemical or mechanical signals.

18. The system for monitoring the status of claim 13 , wherein the external communication device is configured to detect damage to the implantable medical device.
