Abstract:
1. A header for an implantable medical device, said device comprising an electronic circuit and a power source contained within a hermetically sealed housing and having a feedthrough with a plurality of input and output pins, the header comprising: (a) a plastic connector module of generally rectangular cross section with a top surface, a bottom surface and first and second side edges, said module having a longitudinal bore adapted to receive a lead connector pin therein, the connector module having a plurality of spaced apart, transversely extending slots formed through one of the first and second side edges of said connector module and intersecting the longitudinal bore and having a corresponding plurality of pin-hole apertures formed in a bottom surface of the connector module and individually intersecting with the plurality of transversely extending slots; (b) a plurality of electrical contact members each contact member including a metal plate having a central aperture formed therethrough, the aperture containing a toroidal, canted-coil, metal spring, one such electrical contact member being individually inserted through each of said slots such that the central aperture of each of the contact members is coaxial with the longitudinal bore; (c) a tubular elastomeric seal member disposed in the longitudinal bore between adjacent ones of the contact members with opposed ends of the seal member abutting adjacent ones of the contact members; and (d) each of said metal plates being conductively attached to an individual one of the input and output pins with the input and output pins passing individually through the plurality of pin-hole apertures formed in the bottom surface of the connector module.
