Feed through interconnect assembly for an implantable stimulation system and methods of making and using
First Claim
1. A stimulation system comprising:
- an implantable pulse generator comprising a sealed chamber and an electronic subassembly disposed in the sealed chamber;
a plurality of feed through pins coupled to the electronic subassembly and extending out of the sealed chamber;
a plurality of feed through interconnects disposed entirely external to the sealed chamber, the feed through interconnects coupled to the feed through pins such that the feed through interconnects are indirectly coupled to the electronic subassembly via the feed through pins, wherein each of the plurality of feed through interconnects is conductive;
at least one contact pad disposed on at least one of the feed through interconnects, wherein the at least one contact pad defines a coupling aperture having a first edge and an opposing second edge; and
at least one flexible tab at least partially disposed within the coupling aperture of the at least one contact pad, the at least one tab having a proximal end and a distal end, the proximal end attached to the first edge of the coupling aperture;
wherein for at least a first contact pad of the at least one contact pads a first feed through pin of the plurality of feed through pins extends through the coupling aperture of the first contact pad, wherein a first side of the first feed through pin contacts the distal end of the at least one tab as the distal end of the at least one tab flexes away from the contact pad and a second side of the first feed through pin, opposite to the first side, contacts the second edge of the coupling aperture.

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.
