Abstract
A connector for an implantable electrical medical device includes a connector lumen defined in an elongated connector housing and adapted for receiving a portion of a lead. Connector-contact assemblies are disposed in the connector lumen and adapted to couple to terminals of the lead when the lead is received by the connector lumen. Each of the connector-contact assemblies includes a contact body. An inner surface of the contact body defines an open center portion. A first base is disposed along a first end of the contact body, and a second base is disposed along an opposing second end of the contact body and is coupled to the first base. Biasing members are attached to the first base and extend towards the second base. The biasing members are not attached to the second base. When the lead is received by the connector lumen the biasing members physically contact the received lead.
