A device for transcutaneous electrical stimulation device for affecting
gastric function in a patient and a method for performing the same is
provided. The device includes a first waveform generator adapted to
generate a first waveform having a first frequency capable of stimulating
a vagus nerve of the patient at a predetermined location, a second
waveform generator adapted to generate a carrier waveform having a second
frequency capable of passing from the surface of skin of the patient at
the predetermined location, through tissue to the vagus nerve, a
modulation device electrically coupled to the first, second and third
waveform generators and adapted to modulate the first and carrier
waveforms to create a modulated signal, and a first electrode
electrically coupled to the modulation device and positioned
substantially adjacent to the skin of the mammal, and adapted to apply
the modulated signal thereto.
