Abstract:
1. A transdermal stimulation device for selectively stimulating a predetermined nerve of a mammal, comprising: a first waveform generator configured to generate a first analog waveform having a selected amplitude and frequency capable of stimulating the predetermined nerve, wherein the generated first waveform is itself incapable of transdermally stimulating the predetermined nerve; a second waveform generator configured to generate a second analog carrier waveform having a selected amplitude and frequency, wherein the frequency of the second carrier waveform is greater than that of the first waveform, wherein the second carrier waveform is capable of passing through the mammal's skin and tissue to reach the predetermined nerve, and wherein the frequency of said generated carrier waveform is itself incapable of electrically stimulating the predetermined nerve; an amplitude modulation device electrically coupled to the first and second waveform generators and configured to multiply the second carrier waveform and the first waveform to create a modulated signal that maintains the modulation envelope and frequency information of the first waveform and second carrier waveform, and that is capable of transdermally electrically stimulating the predetermined nerve, wherein the predetermined nerve is the pudendal nerve; and an active electrode electrically coupled to the modulation device and positioned substantially adjacent to the skin of the mammal, the active electrode being configured to apply the modulated signal to the skin.
