Abstract
In one embodiment, a neurostimulation lead for stimulating neural tissue of a patient, comprises: a lead body of insulative material; a plurality of electrodes; a plurality of terminals; a plurality of conductors, wherein the plurality of electrodes are electrically coupled to the plurality of terminals through the plurality of conductors; wherein the plurality of conductors are disposed in a helical manner in a repeating pattern of groups of conductors separated by gaps along a substantial length of the lead body, each gap being larger than an inter-conductor pitch within the groups of conductors; wherein the insulative material is a compliant material permitting elongation of the lead at low stretching forces and the insulative material of the lead body is fused through a substantial volume of the lead body and along a substantial length of the lead body.
