Abstract

An implantable medical device (IMD) includes a core assembly having a housing with circuitry disposed therein. The IMD also includes an integrated electrode/antenna assembly. The integrated electrode/antenna assembly includes an electrode component and an antenna component.

Claims

1. An implantable medical device (IMD), comprising:

a core assembly comprising a housing having circuitry disposed therein;

a header comprising an exterior surface that encloses an interior region; and

an integrated electrode/antenna assembly, wherein the integrated electrode/antenna assembly comprises an electrode component and an antenna component.

2. The IMD of claim 1, further comprising a scaffold assembly configured to position at least a portion of the integrated electrode/antenna assembly within the interior region of the header.

3. The IMD of claim 2, wherein the antenna component is offset from the electrode component.

4. The IMD of claim 3, wherein the electrode is disposed adjacent a first outside surface of the header.

5. The IMD of claim 4, wherein the IMD is configured to be implanted in a patient such that the first outside surface of the header faces in a direction toward the inside of the patient'"'"'s body, and a second outside surface of the header faces in a direction away from the inside of the patient'"'"'s body.

6. The IMD of claim 1, wherein the antenna component comprises a conducting ribbon.

7. The IMD of claim 1, wherein the antenna component comprises a bent wire forming a bent monopole antenna.

8. The IMD of claim 1, wherein the antenna component comprises:

a driven element electrically coupled to the circuitry; and

a reflector comprising a ground-plane disposed on at least a portion of an internal surface of the header, wherein the electrode component functions as a director.

9. The IMD of claim 8, wherein the driven element comprises a biased field effect transistor (FET) or a folded dipole.

10. The IMD of claim 1, wherein at least one of the antenna component and the electrode component comprises a conductive patch.

11. The IMD of claim 10, wherein the conductive patch is electrically coupled, via a feedthrough, to the circuitry disposed within the core assembly.

12. A system, comprising:

an implantable medical device (IMD) configured to be implanted within the body of a patient, the IMD comprising;

a core assembly comprising a housing having circuitry disposed therein;

a header comprising an exterior surface that encloses an interior region; and

an integrated electrode/antenna assembly; and

a receiving device configured to communicate with the IMD via a wireless communication link.

13. The system of claim 12, the wireless communication link comprising a Bluetooth link.

14. The system of claim 12, wherein the integrated electrode/antenna assembly comprises an electrode component and an antenna component.

15. The system of claim 14, wherein the electrode component comprises a conducting ribbon.

16. The system of claim 14, wherein the antenna component comprises a bent wire forming a bent monopole antenna.

17. The system of claim 14, wherein the antenna component comprises a conductive patch.

18. An implantable medical device (IMD), comprising:

a core assembly comprising a housing having circuitry disposed therein;

a header comprising an exterior surface that encloses an interior region; and

an integrated electrode/antenna assembly at least partially disposed within the interior region of the header.

19. The IMD of claim 18, wherein the integrated electrode/antenna assembly comprises an antenna component and an electrode component.

20. The IMD of claim 19, wherein the antenna component comprises:

a driven element electrically coupled to the circuitry; and

a reflector comprising a ground-plane disposed on at least a portion of an internal surface of the header, wherein the electrode component functions as a director.
