Abstract
An implantable medical device connector assembly and method of manufacture include a molded, insulative shell having an inner surface forming a connector bore, a circuit member including one or more traces extending through apertures in the connector shell. One or more conductive members, positioned along the connector bore, are electrically coupled to the traces. The sealing members are positioned between the conductive members.
