Implantable feedthrough-based connector

An implantable connector electrically connects multi-conductor leads to an implantable medical device such as a neurostimulator. The connector is applicable to a variety of lead contact terminals, including iso-diametric terminals with ring contacts, paddle-shaped terminals with flat pad contacts, and orthogonal lead contact terminals. The connector is assembled directly into a hermetic feedthrough of the device and utilizes the feedthrough housing as a sustaining structure for connector pressurization. The feedthrough pins are integrated with compressible contacts in a manner that confines, protects, and precisely positions the compressible contacts. The compressible contacts can be coil springs, metal-particle-filled elastomer buttons, and fuzz buttons, and can be used with rigid tips where a contact preload and/or an enhanced contact tip robustness is desired. Connector pressurization means include covers fastened with a screw and cam actuated clamping covers which support contact forces and the seal compression by engaging undercuts on the feedthrough housing walls.
