1. An introducer system comprising:
an electrical stimulus generator;
an open-coiled stimulation lead having a conductive distal anchor, a proximal end in communication with the electrical stimulus generator and a centrally disposed axial void;
a needle assembly comprising a first needle comprising an outer sheath having an outer circumference and defining a bore wherein the outer circumference is not continuous, a second needle carried within the bore during positioning and testing of the open-coiled stimulation lead, and at least one test electrode positioned along the outer circumference and in electrical communication with the electrical stimulus generator; and
a third needle comprising a third needle sheath having a third needle outer circumference and defining a third needle bore wherein the open-coiled stimulation lead is carried within the third needle sheath, whereby the open-coiled stimulation lead and the third needle sheath replace the second needle in preparation for deployment of the open-coiled stimulation lead.
