An electro-nerve stimulator system includes a pulse generator for generating current pulses with a transcutaneous patch and percutaneous needle for delivering current pulses to selected stimulation sites. The stimulator is a small battery operated external device that allows adjustment of stimulation levels and interfaces, via a connector, to the trans-percutaneous cable. The transcutaneous electrode is attached to the skin distal from the desired stimulated nerve site. A percutaneous needle is inserted close to the internal nerve site. Stimulation current pulses are designed to flow between the transcutaneous electrode and the internal percutaneous needle. The field generated at the needle site causes the nerve to fire.
