| 7. A method of fabricating a lead for spinal neurological stimulation, comprising:
providing a first insulator layer; spirally wrapping a plurality of conductors about the first insulator layer;
spirally wrapping at least one insulating spacer about the first insulator layer in between at least two adjacent conductors
of the plurality of conductors;
providing a second insulator layer over the plurality of conductors and the at least one insulating spacer;
fusing the first insulator layer, the at least one insulating spacer, and the second insulator layer to each other to form
a lead body, wherein the plurality of conductors and the at least one insulating spacer extend substantially along the length
of the lead body, the at least one spacer maintaining a pitch between the at least two adjacent conductors substantially along
the length of the lead body; and
forming a lead, from the lead body, for spinal neurological stimulation, the lead comprising a plurality of electrodes.
