Abstract
A connector assembly includes a ring sub-assembly mounted on the housing of an implantable medical device with a passage for slidably receiving a proximal terminal of an electrical lead. The interior of the connector assembly is sealed when engaged with the electrical lead and has an annular shoulder in the passage facing away from the entrance. An electrical contact on the ring sub-assembly engages the electrical lead and an electrical conductor extends from that contact to exterior regions for electrical engagement with an external feed-through terminal of the housing. A tip sub-assembly having a tubular extremity extending to a terminal rim is fittingly received within the passage and extends to a terminal bore for slidably receiving a tip electrode of the electrical lead. An electrically conductive resilient member is received in the passage sandwiched between the annular shoulder and the terminal rim of the tubular extension and is electrically coupled to the electrical contact of the connector assembly.
