1. A nerve stimulation lead with a distal end, a proximal end, and a longitudinal length, the nerve stimulation lead comprising:
- a plurality of electrodes disposed at the distal end;
a plurality of terminals disposed at the proximal end;
a plurality of conductive wires electrically coupling the plurality of electrodes electrically to the plurality of terminals; and
at least one anchoring unit disposed on the nerve stimulation lead, the at least one anchoring unit configured and arranged for anchoring the nerve stimulation lead against a bony structure or against soft tissue abutting a bony structure, wherein each of the at least one anchoring units is configured and arranged to transition between an undeployed position and a deployed position, the undeployed position facilitating positioning of the nerve stimulation lead and the deployed position for anchoring the nerve stimulation lead, wherein the at least one anchoring unit transitions from an undeployed position to a deployed position by twisting at least a portion of the nerve stimulation lead.
