Abstract:
1. An implantable lead configured to be coupled to an implantable pulse generator header having a connector port including a plurality of axially-spaced header contact elements, the lead comprising: a flexible lead body having a proximal end, a distal end portion, and a plurality of conductor lumens extending axially within the lead body from the proximal end to the distal end portion; a plurality of conductor wires, each conductor wire extending within one of the conductor lumens in the lead body; a plurality of electrodes coupled to the lead body in the distal end portion thereof, each of the electrodes being electrically coupled to at least one of the plurality of conductor wires; and a terminal connector assembly coupled to the proximal end of the lead body, the terminal connector assembly sized to be inserted into and received by the connector port of the pulse generator header and including a plurality of axially spaced terminal ring elements each electrically coupled to at least one of the conductor wires, the terminal ring elements separated from one another by an electrically insulating material having an outer surface, the terminal ring elements each having an outer surface aligned with the outer surface of the electrically insulating material and having a first portion and a second portion, the first portion being electrically conductive and the second portion being electrically non-conductive, and a plurality of electrically conductive flexible rings, the electrically conductive flexible rings each being arranged on the outer surface of the terminal ring elements at the first portion and configured to provide electrical connections to the pulse generator header.
