1. An assembly for forming a stimulation lead, comprising:
- a lead body having a distal end and a proximal end; and
a pre-electrode assembly formed in a tube around a portion of the distal end of the lead body and comprising a plurality of segmented electrodes and a plurality of raised connectors, wherein the segmented electrodes form at least one helix or spiral, wherein each of the segmented electrodes is coupled to at least one other of the segmented electrodes by at least one of the raised connectors and the segmented electrodes and the raised connectors are formed of a same conductive material, the tube defining a longitudinal axis, wherein each of the raised connectors is disposed at a radius with respect to the longitudinal axis that is greater than a radius of any of the segmented electrodes with respect to the longitudinal axis, wherein each of the segmented electrodes is attached to one of the raised connectors at an angle in a range of 10 to 80 degrees with respect to an edge of that segmented electrode.

Abstract
A stimulation lead includes a lead body having a longitudinal surface, a distal end, a proximal end, and a shaft extending along at least a portion of the distal end of the lead body. The stimulation lead also includes multiple segmented electrode members disposed on the shaft along the longitudinal surface of the lead body near the distal end of the lead body. Each segmented electrode member includes a ring structure which forms at least a partial ring and is disposed on the shaft, and a segmented electrode coupled to the ring and having an exposed surface configured and arranged for stimulating tissue when the stimulation lead is implanted.
