Implantable pulse generator and method of use
First Claim
1. A medical implantable pulse generator system comprising:
- a housing enclosing pulse generating circuitry;
a plurality of feed-through wires coupled to the pulse generating circuitry and extending through the housing;
a lead having a plurality of terminals;
a header coupled to the housing, the header comprising;
a port adapted to receive an end of the lead,an inner guide having a plurality of transverse bores positioned to correspond to the plurality of feed-through wires such that the inner guide is slidingly coupled to the plurality of feed-through wires, wherein the inner guide has an exterior longitudinal surface intersecting a portion of each bore of the plurality of transverse bores to create an exposed portion of each feed-through wire of the plurality of feed-through wires,an outer seal having an interior surface sized to support the plurality of terminals such that each terminal is maintained against the exposed portion of a corresponding feed-through wire, anda clip component coupled to the outer seal and biased to compress against the outer seal to create compression forces on the outer seal, andwherein a plurality of longitudinal curved exterior surfaces are defined on the outer seal and a plurality of longitudinal detents are defined by the clip component which are shaped to fit within the plurality of longitudinal curved exterior surfaces.

22. A method of assembling an implantable pulse generator system, comprising:
-
providing pulse generating circuitry within a housing; providing feed-through wires to permit electrical access to the pulse generating circuitry within the housing; coupling the feed-through wires to an inner guide to maintain the position of the feed-through wires and to create an exposed portion of each feed-through wire, surrounding a portion of the inner guide with an outer seal to create a void proximal to the exposed portion of each feed-through wire, inserting terminals of a lead into the void, connecting the exposed portions of the feed-through wires to the corresponding terminals, and applying compressive forces to the terminals to maintain the terminals against the exposed portions of the feed-through wires; wherein the applying compressive forces includes positioning a biasing member over the outer seal to compress the outer seal such that the outer seal applies compressive forces to the terminals; wherein the positioning a biasing member includes positioning longitudinal detents of a clip component over longitudinal curved surfaces of the outer sea.
