Threaded connector assembly and methods of making and using the same

A connector assembly comprising:

• a lead comprising a lead body having a proximal portion and a distal portion and defining a longitudinal axis, the lead further comprising a plurality of terminals disposed along the proximal portion of the lead body and a proximal tip attached to the proximal portion of the lead body, the proximal tip defining an aperture that is non-parallel to the longitudinal axis of the lead body;
• a connector comprising a connector body, a connector lumen, and a plurality of connector contacts disposed within the connector body and adjacent the connector lumen, the connector body comprising a fastener aperture proximal to all of the connector contacts and intersecting the connector lumen, wherein the fastener aperture of the connector and aperture of the proximal tip of the lead are configured and arranged for alignment when the proximal portion of the lead body is fully received within the connector lumen, wherein one of the aperture of the proximal tip of the lead or the fastener aperture of the connector comprises internal threading;
• and
• a threaded fastener configured and arranged for insertion into the aperture of the proximal tip of the lead and the fastener aperture of the connector and engaging the internal threading to fasten the lead to the connector.
