Abstract

A stimulation system includes an implantable pulse generator having a sealed chamber and an electronic subassembly disposed in the sealed chamber. Feed through pins are coupled to the electronic subassembly and extend out of the sealed chamber. Feed through interconnects are coupled to the electronic subassembly via the feed through pins. At least one tab is disposed on at least one feed through interconnect. The tab(s) are configured and arranged to flex away from the feed through interconnect and against a side of the feed through pin.

A feed through interconnect assembly includes an assembly frame; feed through interconnects extending from the assembly frame; a first contact pad and a second contact pad disposed on at least one of the feed through interconnects; and a tab formed on a first contact pad of at least one of the feed through interconnects.

Claims

1. A feed through interconnect assembly comprising:

an assembly frame having a first side and an opposing second side;

a plurality of feed through interconnects directly attached to the assembly frame, wherein a first set of the feed through interconnects extend inwardly, with respect to the assembly frame, from, and are directly attached to, the first side of the assembly frame, and wherein a second set of the feed through interconnects extend inwardly, with respect to the assembly frame, from, and are directly attached to the second side of the assembly frame, wherein the feed through interconnects and the assembly frame are made of a same conductive material;

a first contact pad and a second contact pad disposed on at least one of the feed through interconnects; and

a tab formed on the first contact pad of at least one of the feed through interconnects.

2. The feed through interconnect assembly of claim 1, further comprising at least one brace formed along a portion of the assembly frame, the at least one brace coupling the assembly frame to at least one of the plurality of feed through interconnects.

3. The feed through interconnect assembly of claim 2, wherein the at least one brace is removable from the assembly frame.

4. The feed through interconnect assembly of claim 1, further comprising a first brace that couples at least one feed through interconnect of the first set of the feed through interconnects to the assembly frame.

5. The feed through interconnect assembly of claim 4, further comprising a second brace that is different from the first brace and couples at least one feed through interconnect of the second set of the feed through interconnects to the assembly frame.

6. The feed through interconnect assembly of claim 1, wherein the first contact pad defines a coupling aperture having a first edge and an opposing second edge.

7. The feed through interconnect assembly of claim 6, wherein the tab has a proximal end and an opposing distal end, and wherein the tab is at least partially disposed within the coupling aperture with the proximal end of the tab attached to the first edge of the coupling aperture.

8. The feed through interconnect assembly of claim 6, wherein the coupling aperture is configured and arranged to receive a feedthrough pin extending from a sealed chamber of an implantable pulse generator.

9. The feed through interconnect assembly of claim 1, wherein the tab is configured and arranged to flex away from the first contact pad.

10. The feed through interconnect assembly of claim 1, further comprising at least one indexing hole defined in the assembly frame and extending entirely through the assembly frame.

11. The feed through interconnect assembly of claim 1, wherein the first contact pad and the second contact pad are disposed on each of the plurality of feed through interconnects.

12. The feed through interconnect assembly of claim 1, wherein the assembly frame is removable from the feed through interconnect assembly.

13. The feed through interconnect assembly of claim 1, wherein the plurality of feed through interconnects are spaced apart from one another at substantially uniform distances.

14. The feed through interconnect assembly of claim 1, wherein the plurality of feed through interconnects are interleaved.

15. The feed through interconnect assembly of claim 1, wherein the plurality of feed through interconnects extend from the assembly frame with the plurality of feed through interconnects extending along a plane of the assembly frame.

16. The feed through interconnect assembly of claim 1, wherein the plurality of feed through interconnects extend from the assembly frame with the plurality of feed through interconnects extending above or below a plane of the assembly frame.

17. The feed through interconnect assembly of claim 1, wherein the conductive material is selected from stainless steel material, platinum, platinum/iridium, or titanium.
