Abstract

An apparatus includes an implantable housing, a header mounted to the implantable housing and including a connector block cavity, and a connector block located within the connector block cavity, the connector block including a plastic housing portion, a coil spring, and a metallic termination member connected to the coil spring and exposed outside the plastic housing portion.

First claim

The claimed invention is:

1. An apparatus comprising:
an implantable housing;
a header mounted to the implantable housing and including a connector block cavity; and
a connector block located within the connector block cavity, the connector block including a plastic housing portion, a coil spring configured to receive a terminal pin, and a metallic termination member connected to the coil spring and exposed outside the plastic housing portion and configured to electrically couple to a feedthrough that extends from the housing to the header, wherein the plastic housing portion includes an outer surface with the metallic termination member lying flush against the outer surface.

2. The apparatus of claim 1 , wherein the metallic termination member is non-circumferential around the coil spring.

3. The apparatus of claim 1 , wherein the connector block cavity is open on a side of the header such that the connector block is side-mounted into the header.

4. The apparatus of claim 1 , wherein the plastic housing portion includes a receiver section configured to receive at least a portion of the coil spring.

5. The apparatus of claim 1 , wherein the plastic housing portion is integral to the header within the connector block cavity.

6. The apparatus of claim 1 , wherein the plastic housing portion includes a discrete plastic housing body mounted within the connector block cavity.

7. The apparatus of claim 1 , wherein the metallic termination member includes a flat ribbon connector.

8. The apparatus of claim 1 , wherein the metallic termination member includes a metallic block including at least a portion configured to receive the coil spring.

9. The apparatus of claim 7 , wherein the plastic housing portion includes a flat, planar outer surface with the flat connector ribbon lying flush against the flat, planar outer surface.

10. The apparatus of claim 1 , wherein the plastic housing portion includes a non-planar outer surface.

11. The apparatus of claim 1 , wherein the metallic termination member includes a flat ribbon connector which extends away from the connector block and connected directly to a feedthrough.

12. The apparatus of claim 1 , wherein the header includes a header core overmolded with an epoxy.

13. An apparatus comprising:
an implantable housing;
a header mounted to the implantable housing and including a plastic header core having a connector block cavity;
a feedthrough extending from the header to the housing; and
a connector block located within the connector block cavity, the connector block including a plastic housing portion holding a spring configured to receive a terminal pin and a metallic termination member connected to the spring and exposed outside the plastic housing portion and configured to electrically couple to a feedthrough that extends from the housing to the header, wherein the plastic housing portion includes an outer surface with the metallic termination member lying flush against the outer surface;
wherein the header core is overmolded with an epoxy to encapsulate the connector block and the header core.

14. The apparatus of claim 13 , wherein the metallic termination member is non-circumferential around the spring.

15. The apparatus of claim 13 , wherein the plastic housing portion includes a receiver section configured to receive at least a portion of the spring.

16. The apparatus of claim 13 , wherein the plastic housing portion is integral to the header within the connector block cavity.

17. The apparatus of claim 13 , wherein the plastic housing portion includes a discrete plastic housing body mounted within the connector block cavity.
