The present invention is directed to a method of regulating
gastrointestinal action in a subject using a stimulatory electrode and a
sensor to provide retrograde feedback control of electrical stimulation to
the GI tract. The invention is further directed to a method for reducing
weight in a subject, again using a stimulatory electrode and a sensor to
provide retrograde feedback control of electrical stimulation to the
stomach. The invention is further directed to a method of providing
electrical field stimulation to a gastrointestinal organ, as well as a
method of providing an electrical potential gradient in a gastrointestinal
organ. Further provided is a method of stimulating the vagus nerve of a
subject. Additionally provided is a method of placing a device in the
gastrointestinal tract or wall of a subject from the exterior of the
subject, using a needle to insert the device.
