Abstract

A implantable active medical device includes a chassis plate having a first major surface and an opposing second major surface, an elongate lead connector fixed to the first major surface and extending orthogonally away from the first major surface and a circuit board fixed to the first major surface and extending orthogonally away from the first major surface. A hermetic housing defines a sealed housing cavity. The hermetic housing is fixed to the first major surface. The elongate lead connector and the circuit board are disposed within the sealed housing cavity.

First claim

What is claimed is:

1. An implantable active medical device comprising:
a chassis plate having a first major surface and an opposing second major surface;
an elongate lead connector configured to receive a lead, wherein the elongate lead connector is fixed to the first major surface and extends orthogonally away from the first major surface;
a circuit board having a length, a width, and a thickness, the length being greater than the width and the thickness, the circuit board fixed to and extending orthogonally away from the first major surface in the direction of the length; and
a hermetic housing defining a sealed housing cavity, the hermetic housing fixed to the first major surface and the elongate lead connector and the circuit board are disposed within the sealed housing cavity.

2. The implantable active medical device according to claim 1 , wherein the elongate lead connector comprises a closed end, an open end hermetically joined to the chassis plate, an outer surface at least partially defining the sealed housing interior, and an inner surface defining a lead aperture.

3. The implantable active medical device according to claim 2 , wherein the elongate lead connector comprises two or more electrically conducting contact rings spaced apart by a ring of electrically insulating material, the two or more electrically conducting contact rings in electrical communication with the circuit board, and the ring of electrically insulating material providing a hermetic seal between the lead connector outer surface and the lead connector inner surface.

4. The implantable active medical device according to claim 1 , further comprising a power source fixed to the chassis plate.

5. The implantable active medical device according to claim 4 , wherein the power source is electrically connected to the circuit board through the chassis plate.

6. The implantable active medical device according to claim 1 , wherein the elongate lead connector is disposed through the chassis plate.

7. The implantable active medical device according to claim 1 , wherein the elongate lead connector is fixed mechanically and electrically to the circuit board.

8. The implantable active medical device according to claim 1 , wherein the elongate lead connector is coextensive with the circuit board.

9. An implantable active medical device according to claim 1 , further comprising a second elongate lead connector fixed to the first major surface and extending orthogonally away from the first major surface.

10. An implantable active medical device according to claim 1 , further comprising a rigid sleeve fixed to the chassis plate and disposed about the elongate lead connector.

11. An implantable active medical device according to claim 10 , wherein the rigid sleeve has a proximal end fixed to the chassis plate and an opposing distal end, the distal end including a mounting surface for fixing the circuit board to the rigid sleeve.

12. An implantable active medical device according to claim 11 , wherein the mounting surface is parallel to the circuit board.

13. An implantable active medical device comprising:
a chassis plate having a first major surface and an opposing second major surface;
a first elongate lead connector configured to receive a lead, wherein the first elongate lead connector is fixed to the first major surface and extends orthogonally away from the first major surface;
a second elongate lead connector configured to receive a lead, wherein the second elongate lead connector is fixed to the first major surface and extends orthogonally away from the first major surface;
a circuit board having a length, a width, and a thickness, the length being greater than the width and the thickness, the circuit board fixed to and extending orthogonally away from the first major surface in the direction of the length, the circuit board being disposed between the first elongate lead connector and the second elongate lead connector; and
a hermetic housing defining a sealed housing cavity, the hermetic housing fixed to the first major surface and the first elongate lead connector, second elongate lead connector and the circuit board are disposed within the sealed housing cavity.

14. The implantable active medical device according to claim 13 , wherein the first elongate lead connector comprises a first closed end, a first open end hermetically joined to the chassis plate, a first outer surface at least partially defining the sealed housing interior, and a first inner surface defining a first lead aperture.

15. The implantable active medical device according to claim 14 , wherein the first elongate lead connector comprises two or more electrically conducting contact rings spaced apart by a ring of electrically insulating material, the two or more electrically conducting contact rings in electrical communication with the circuit board, and the ring of electrically insulating material providing a hermetic seal between the first lead connector outer surface and the first lead connector inner surface.

16. The implantable active medical device according to claim 13 , further comprising a power source fixed to the second major surface.

17. The implantable active medical device according to claim 16 , wherein the power source is electrically connected to the circuit board through the chassis plate.

18. The implantable active medical device according to claim 13 , wherein the first elongate lead connector is disposed through the chassis plate and the second elongate lead connector is disposed through the chassis plate.

19. The implantable active medical device according to claim 13 , wherein the first elongate lead connector is fixed mechanically and electrically to the circuit board and the second elongate lead connector is fixed mechanically and electrically to the circuit board.

20. The implantable active medical device according to claim 13 , wherein the first elongate lead connector is coextensive with the circuit board and the second elongate lead connector is coextensive with the circuit board.

21. The implantable active medical device according to claim 20 , wherein the circuit board separates the first elongate lead connector from the second elongate lead connector.

22. An implantable active medical device according to claim 13 , further comprising a rigid sleeve fixed to the chassis plate and disposed about the first elongate lead connector.

23. An implantable active medical device according to claim 22 , wherein the rigid sleeve has a proximal end fixed to the chassis plate and an opposing distal end, the distal end including a mounting surface for fixing the circuit board to the rigid sleeve.

24. An implantable active medical device according to claim 23 , wherein the mounting surface is parallel to the circuit board.
