Abstract:
1. An electrical contact for use in the header assembly of an implantable cardiac rhythm management device for mating with a terminal pin of a tissue stimulating lead comprising: (a) a metal retainer having a base with a sidewall, an opening in the base sized to receive a lead terminal pin therethrough with a predetermined non-contact clearance; (b) a flat, toroidal electrical contact support member having an outside shape permitting placement on an exposed edge of the sidewall of the retainer and a central opening of a diameter generally equal to that of the opening in the base of the retainer; and (c) a plurality of spring members integrally attached to a conductive ring at equally circumferentially spaced locations, the ring being concentric with and attached to the electrical contact support member, said spring members projecting inwardly of the diameter of the central opening of the electrical contact support member and adapted to provide an interference fit with a lead terminal pin inserted through said opening in the base of the retainer and through the central opening of the electrical contact support member.
