First Claim
1. An electrical stimulation lead comprising:
- a lead body having an outer surface, a proximal end, a proximal portion, at least one distal portion, an outer surface, a perimeter, and a longitudinal length, the lead body defining an alignment groove extending distally from the proximal end of the lead body and extending inwardly from the outer surface of the lead body;
a plurality of electrodes disposed along the distal portion of the lead body;
a plurality of segmented terminals disposed along the proximal portion of the lead and arranged in a plurality of sets of segmented terminals, wherein each set of segmented terminals comprises at least two of the segmented terminals disposed in a circumferential arrangement at a same longitudinal position of the lead, wherein each segmented terminal extends around less than the entire perimeter of the lead and is separated from all other segmented terminals by portions of the lead body; and
a plurality of lead conductors electrically coupling the plurality of electrodes to the plurality of segmented terminals.

Abstract
An electrical stimulation lead includes a lead body that defines an alignment feature extending distally from a proximal end of the lead body and inwardly from an outer surface of the lead body. The lead also includes electrodes disposed along the distal portion of the lead body, segmented terminals disposed along the proximal portion of the lead and arranged in sets of segmented terminals, and lead conductors electrically coupling the electrodes to the terminals. Each set of segmented terminals includes at least two segmented terminals disposed in a circumferential arrangement at a same longitudinal position of the lead. A system can include the lead and a connector for receiving the proximal end of the lead. The connector can include an alignment protuberance extending into a connector lumen and configured to be received into the alignment groove of the lead to align the lead with the connector.
