Patent ID: 8909352

Claim:
An implantable electrical stimulation lead comprising: a lead body having a distal end, a proximal end, and a longitudinal length; a plurality of electrodes disposed on the distal end of the lead body; a plurality of terminals disposed on the proximal end of the lead body; and a plurality of conductors electrically coupling the plurality of electrodes to at least one of the terminals, the plurality of conductors comprising: a first conductor arranged into a plurality of first coiled regions and a plurality second coiled regions, wherein the first coiled regions are arranged into multiple layers of coils, and wherein the second coiled regions are arranged into single layers of coils, wherein the first coiled regions and the second coiled regions alternate along the longitudinal length of the lead body, wherein the first coiled regions have tighter pitches than the second coiled regions, wherein the first coiled regions and the second coiled regions each coil along the longitudinal length of the lead body exclusively in a single direction, and a second conductor arranged into a plurality of third coiled regions and plurality of fourth coiled regions, wherein the third coiled regions and the fourth coiled regions alternate along the longitudinal length of the lead body, wherein the third coiled regions have tighter pitches than the fourth coiled regions, wherein the third coiled regions and the fourth coiled regions each coil along the longitudinal length of the lead body exclusively in a single direction; wherein the plurality of conductors are arranged into repeating adjacent winding geometries disposed along the longitudinal length of the lead body, the repeating adjacent winding geometries each comprising one of the plurality of first coiled regions and one of the plurality of third coiled regions disposed adjacent to one another along the longitudinal length of the lead body and one of the plurality of second coiled regions extending either over or beneath the one of the plurality of third coiled regions.
