Abstract:
1. A method of electrically stimulating the lower esophageal sphincter comprising the steps of: a) arranging a plurality of electrode sets within a portion of the gastro-intestinal tract wherein electrical stimuli from the electrode sets causes the lower esophageal sphincter to contract; b) applying electrical stimuli the plurality of electrode sets wherein the electrical stimuli prevent transient relaxation of the LES and/or increase the tone of the LES c) said plurality of electrode sets for stimulating the lower esophageal sphincter including pH sensors for detecting change in esophageal pH due to acid reflux; and d) applying sensing electrodes in the esophagus for detecting esophageal peristalsis so as to inhibit the electrical stimulation of the lower esophageal sphincter in order to pass food to the stomach.
