Patent ID: 8437856

Claim:
A medical device lead connector system comprising: a lead having a lead body, a plurality of elongated insulated conductors extending within the lead body between a plurality of lead electrodes at a lead body distal end and a lead body proximal end; a lead connector at the lead body proximal end, wherein the lead connector extends along a longitudinal axis and includes an array of lead connector pads, wherein the pads are distributed circumferentially in an adjacent spaced apart relationship around a periphery of the lead connector such that a plane perpendicular to the longitudinal axis of the lead connector intersects with more than one of the lead connector pads of the array of lead connector pads, wherein lead connector pad of the array of lead connector pads is electrically coupled to one lead electrode of the plurality of lead electrodes through one elongated insulated conductor of the plurality of elongated insulated conductors, and an adaptor comprising: an insulating adaptor body having a proximal end and a distal end; a lumen within the adaptor body having an inner lumen surface extending from a proximal end to a distal end and dimensioned to receive the lead connector for relative rotational movement therein, and an electrical connector extending circumferentially over a segment of an exterior surface of the adaptor body, the electrical connector extending through the insulating adaptor body and forming a key on the inner lumen surface, the key dimensioned so as to be in registration with only one selected lead connector pad of the array of lead connector pads at a time when the lead connector is inserted into the lumen of the adaptor body, wherein the electrical connector is electrically coupled with the lead electrode coupled to the selected lead connector pad through the elongated insulated conductor.
