Abstract
A nerve stimulation device includes a first waveform generator adapted to generate a first waveform having a first frequency capable of stimulating nerves within a dermatome, a second waveform generator adapted to generate a first carrier waveform having a second frequency capable of passing through tissue of a mammal, and a third waveform generator adapted to generate a second carrier waveform having a third frequency different than the second frequency and being capable of passing through the tissue of the mammal. The device includes a modulator electrically coupled to the first, second and third waveform generators and adapted to modulate the first waveform, the first carrier waveform, and the second carrier waveform to generate a modulated signal package capable of stimulating the nerves at different depths within the dermatome. The device also has an electrode electrically coupled to the modulator for applying the modulated waveform to the dermatomic region.
