gastric pacemaker insertion weight loss device procedure

Gastric Pacemaker for Weight Loss;

The Implantable Gastric Stimulator (IGS) requires an approximately 1-hour laparoscopic insertion time using 4-6 trocar sites; Separate, earlier, ongoing work on gastric stimulation, appears to have been focused on treatment of the disturbances in gastric rhythm that accompany gastroparesis; There are very few published studies examining the role of the gastric pacemaker in weight loss; The gastric pacemaker procedure used to induce weight loss uses a special, disposable, needle inserter; This insertion tool assists the surgeon in tunneling a permanently implanted, but readily removable, metal, bipolar, pacemaker electrode into place about 1 inch long beneath the sero-muscularis of the stomach; The pacemaker electrode is then attached by a well-insulated wire to its battery-powered stimulator implanted in a small subcutaneous pocket deep in the skin and subcutaneous tissue of the left upper abdomen; From there, the stimulator sends programmed electrical impulses to its pacemaker electrode within the gastric wall and may receive diagnostic information in return; Programming and reading of internally derived information is performed in a manner somewhat analogous to that of cardiac pacemaker implants
