Abstract
A connector system for use in coupling an implantable electrical lead to an implantable pulse generator, or other implantable electrical apparatus. The connector system includes a connector pin assembly, typically mounted to the implantable lead and a connector block, typically mounted to the electrical stimulator. The connector block is provided with a lumen, in which a plurality of resilient, elastomeric rings are linearly arranged. The rings are so sized as to frictionally engage a connector pin which is provided with a plurality of conductive pads, each coupled to a conductor within the implantable lead. Certain ones of the elastomeric rings are conductive, and engage with the conductive pads on the connector pin. Others of the rings are nonconductive and act as insulators and fluid seals. The connector pin assembly is also provided with a circumferential groove, which interlocks with the deflectable beam members of a retainer mounted to the connector block. An alternative connector block embodiment employs a metallic spring element to contact conductive areas on the connector pin.
