Claim Text:
1. A ringlet coupler employed in the header of an implantable pulse generator and adapted to make an electrical connection with a contact of a lead pin of a medical lead, said ringlet coupler comprising: (a) an electrical conductive housing comprising an outer cylindrical wall defining a first inner surface and a first outer surface with a pair of cylindrical walls extending inwardly from the first inner surface of the outer cylindrical wall of the housing; (b) an electrically conductive ringlet comprising a band having a second inner surface and a second outer surface, said band fabricated into at least three smoothly curved foils joined together by smoothly curved reduced diameter sections between adjacent foils, wherein said foils are equally spaced about a channel defined by said reduced diameter sections, wherein each foil has an apex adjacent to the inner surface of the housing, wherein the reduced diameter sections are adapted to simultaneously engage a lead pin inserted into the channel to form an electrical connection and cooperate with the foils and the housing to mechanically secure such a lead pin to the electrically conductive ringlet; and (c) means for securing the ringlet to the housing.
