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.
