Patent ID: 8065008

Claim:
A medical device lead connector system comprising: a connector header including a connector bore, the connector bore having an inner bore surface; 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 connector at a 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, and a connector pin proximal of the array of lead connector pads, the connector pin being coupled to one of the plurality of lead electrodes, and each of the lead connector pads being coupled to an individual one of the other of the plurality of lead electrodes; 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 a connector ring extending circumferentially over a segment of an exterior surface of the adaptor body and shaped to form an electrical contact resilient key along an inner portion of the connector ring extending through the insulating adaptor body into the lumen to project from the inner lumen surface, the key dimensioned so as to be in registration with a selected one of the lead connector pads at a time when the lead connector is inserted into the lumen of the adaptor body and rotated relative to the adaptor body about a longitudinal axis extending from the proximal end of the insulating adaptor body to the distal end of the insulating adapter adaptor body so as to be in alignment with the selected lead connector pad; wherein registration of the key with a selected one of the lead connector pads at a time provides for lead electrode array selectivity; and wherein the insulating adaptor body is dimensioned to be received within the connector bore of the connector header.
