1. A method comprising the steps of:
providing an introducer needle preloaded with a coiled lead having an insulated portion and an electrode formed from a deinsulated portion;
percutaneously inserting the introducer needle into a body at an angle at a puncture site;
depositing the electrode outside a spinal column in a region having a spinal nerve that is between a painful region and a center of the body of a patient,
placing a surface stimulation return electrode on the body;
electrically coupling the coiled lead to a pulse generator;
coupling the surface stimulation return electrode to the pulse generator; and
stimulating the spinal nerve to recruit target fibers in the spinal nerve while minimizing recruitment of non-target fibers in the spinal nerve, wherein the electrode is within electrical proximity to and physically spaced from the spinal nerve.
