In-line pacemaker connector system
First Claim
1. A system for coupling an electrical lead to an electrical device, comprising:
- a connector housing means for mounting to said electrical device, including a longitudinal lumen having a proximal end and a distal end and open at its distal end and including at least one electrical connector within said lumen;
deflectable beam retainer means mounted to said connector housing means at the distal end of said longitudinal lumen, said retainer means comprising a plurality of deflectable beams extending distally from said connector housing, arranged around the distal end of the lumen of said connector housing, said deflectable beams generally defining an inner diameter, each of said beams including an inwardly curved portion; and
connector pin means for coupling to said electrical lead, said connector pin means including at least one connector surface and adapted to be inserted into the lumen of said connector block such that said connector surface may electrically engage said electrical connector within the lumen of said connector housing, said connector pin means further provided with a retainer engaging segment adapted to engage with said deflectable beam retainer means, said segment generally having a first outer diameter and including a reduced diameter segment for engaging said curved portions of said deflectable beams whereby when said pin is inserted into said connector housing it is retained by interaction of said deflectable beam retainer means and said retainer engaging segment.

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.
