Endoscopic lead implantation method
First Claim
1. A method of implanting electrically conductive leads in gastrointestinal musculature of a patient utilizing an endoscopic approach, comprising the steps of:
- inserting an endoscope into an esophagus of a patient;
identifying a lower esophageal sphincter (LES);
entering a gastrointestinal (GI) wall with an electrically conductive lead from a mucosal side by puncturing a mucosa of an anterior segment of a region encompassing the LES;
creating a tunnel in a submucosa of the anterior segment of the region encompassing the LES, the tunnel exiting the GI wall through a muscularis propria, adventitia, or serosal side of a stomach of the patient;
navigating the lead through the tunnel to an anterior abdominal wall; and
exiting a second end of the lead through the anterior abdominal wall while leaving a first end of the lead in the gastrointestinal musculature of the patient within the tunnel, wherein the region encompassing the LES comprises an area 3 cm above and 3 cm below the LES.

Abstract
A method of implanting electrically conductive leads in the gastrointestinal musculature for stimulation of target tissues involves an endoscopic approach through the esophagus. An endoscope is inserted into the esophagus of a patient. The mucosal surface of the anterior esophagus is punctured in the region encompassing the lower esophageal sphincter (LES). A tunnel is created through the submucosa and exits at the muscularis propria, adventitia, or serosal side of the stomach. The lead is navigated further to the anterior abdominal wall. A first end of the lead remains within the gastrointestinal musculature while a second end of the lead is positioned just outside the anterior abdominal wall. The first end of the lead comprises at least one electrode. An implantable pulse generator (IPG) is implanted and operably connected to the second end of the lead to provide electrical stimulation to target tissues.

22. A method of implanting electrically conductive leads in the gastrointestinal musculature of a patient utilizing an endoscopic approach, comprising:
-
inserting an endoscope into an esophagus of a patient; advancing said endoscope to an implantation site along a gastrointestinal tract of said patient; entering a gastrointestinal (GI) wall with an electrically conductive lead from a mucosal side by puncturing a mucosa of an anterior segment of said implantation site; creating a tunnel in a submucosa of the anterior segment of said implantation site, the tunnel exiting the GI wall through a muscularis propria, adventitia, or serosal side of a stomach of the patient; navigating a second end of said lead, exiting the GI wall through the tunnel, to a predetermined endpoint within an abdomen of said patient; and leaving a first end of said lead in the gastrointestinal musculature at said implantation site within the tunnel. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
