Abstract

This document describes an apparatus including an implantable medical device having a printed circuit board. The apparatus can include a connector block for a lead terminal of the implantable medical device mounted directly to the printed circuit board.

First claim

What is claimed is:

1. An apparatus comprising:
an implantable medical device including a printed circuit board;
an implantable lead having a distal portion having an electrode and a proximal portion having a lead terminal; and
a connector block for directly connecting to the lead terminal of the implantable lead, the connector block being located directly on and mounted directly on a surface of the printed circuit board.

2. The apparatus of claim 1 , including a filter capacitor located within a body of the printed circuit board and located beneath the connector block.

3. The apparatus of claim 2 , wherein the filter capacitor includes a plurality of plate layers embedded within the body of the printed circuit board.

4. The apparatus of claim 2 , wherein the printed circuit board includes a plurality of laminated layers, with at least one layer located above the filter capacitor and at least one layer located beneath the capacitor.

5. The apparatus of claim 1 , wherein the connector block includes a gold plated plate attached to one side which is soldered or spot welded to the printed circuit board.

6. The apparatus of claim 1 , wherein the printed circuit board further includes one or more integrated circuits embedded within the body of the circuit board.

7. The apparatus of claim 1 , further including one or more electronic components coupled to the printed circuit board and configured to perform signal analysis for providing electric therapy to a body, and further including a power supply coupled to the printed circuit board.

8. The apparatus of claim 7 , wherein the connector block, the printed circuit board, the one or more electronic components, and the power supply are encapsulated within an overmolded polymer material.

9. The apparatus of claim 8 , including one or more ports within the overmolded polymer material to provide access to the connector block for the lead terminal.

10. The apparatus of claim 1 , wherein the connector block includes a metallic housing and a contact spring within the housing for receiving the lead terminal.

11. An apparatus comprising:
an implantable medical device including a printed circuit board;
an implantable lead having a distal portion having an electrode and a proximal portion having a lead terminal;
a connector block for directly connecting to the lead terminal of the implantable lead, the connector block being located directly on and mounted directly on a surface of the printed circuit board;
a filter capacitor located within a body of the printed circuit board and located beneath the connector block; and
wherein the connector block and the printed circuit board are encapsulated within an overmolded polymer material.

12. The apparatus of claim 11 , wherein the filter capacitor includes a plurality of plate layers embedded within the body of the printed circuit board.

13. The apparatus of claim 11 , wherein the printed circuit board includes a plurality of laminated layers, with at least one layer located above the filter capacitor and at least one layer located beneath the capacitor.

14. The apparatus of claim 11 , wherein the connector block includes a gold plated plate attached to one side which is soldered or spot welded to the printed circuit board.

15. The apparatus of claim 11 , wherein the printed circuit board further includes one or more integrated circuits embedded within the body of the circuit board.

16. The apparatus of claim 11 , further including one or more electronic components coupled to the printed circuit board and configured to perform signal analysis for providing electric therapy to a body, and further including a power supply coupled to the printed circuit board.

17. A method comprising:
providing an implantable lead having a distal portion having an electrode and a proximal portion having a lead terminal;
locating and connecting a connector block directly on a surface of a printed circuit board, the connector block for directly connecting to the lead terminal of the implantable lead;
providing a filter capacitor within a body of the printed circuit board and beneath the connector block; and
encapsulating the connector block and the printed circuit board with an overmolded polymer material.

18. The method of claim 17 , wherein connecting the connector block includes connecting a gold plated plate on the connector block to a trace of the printed circuit board.

19. The method of claim 17 , wherein the filter capacitor is embedded within the body of the printed circuit board.

20. The method of claim 19 , wherein the printed circuit board includes a plurality of laminated layers, with at least one layer located above the filter capacitor and at least one layer located beneath the capacitor.
