Electro-nerve stimulator systems and methods

An apparatus for electro-nerve stimulation, the apparatus comprising:

• a pulse generator, wherein the pulse generator includes a DC blocking capacitor electrically coupled to a transcutaneous electrode, a battery for providing current, an oscillator circuit means electrically coupled to the battery for providing current pulses, pulse shaping means electrically coupled to the oscillator circuit means for shaping the current pulses from the oscillator circuit means, DC-DC step up voltage means electrically coupled to the battery and the DC blocking capacitor for changing a DC voltage provided by the battery, and feedback control means electrically coupled to a percuanteous needle and to the pulse shaping means for adjusting the current,
• a transcutaneous electrode electrically coupled to the pulse generator for delivering pulses from the pulse generator to a patient's skin, and
• a percutaneous electrode electrically coupled to the pulse generator and having an end for insertion into a patient's body in proximity to an internal stimulation site to receive pulses from the transcutaneous electrode.
