Problems solved by technology

Furthermore, in the case of patients with pre-existing structural disorders of the gastrointestinal tract (hiatal hernia), suitable lead prevention is difficult to achieve
Often, lead electrodes are not placed optimally close to the target tissue
Also, if the lead is not properly anchored, it will become dislodged and the treatment will become ineffective

Embodiment Construction

[0046] This specification discloses a laparoscopic implantation of a movable plurality of stimulation leads into the wall of the esophagus for use in the treatment of at least one gastrointestinal disorder such as gastroesophageal reflux disease (GERD) electrical stimulation system use together. In various embodiments, a stimulation lead is defined as a lead having one or more stimulation electrodes. In one embodiment, the stimulation lead comprises a straight lead having one stimulation electrode. In one embodiment, the stimulation lead comprises a bipolar lead having two stimulation electrodes. It should be understood that stimulation leads having any number of stimulation electrodes may be used with the methods of the present description. The distal end of the laparoscope is inserted into the patient's abdominal cavity through an incision in the patient's abdominal wall. The doctor then exposes at least 2 cm of the abdominal esophagus. At least one stimulation lead is p...

Abstract

A method of laparoscopically implanting an electrically stimulating lead proximate the lower esophageal sphincter (LES) of a patient includes delivering the lead through a port of a laparoscope inserted into the abdominal cavity of the patient through an incision in the abdominal wall. The stimulating electrode is implanted in or proximate the muscularis layer of the lower esophageal wall to treat esophageal reflux disease (GERD). The lead includes a needle and suture at its distal end for pulling the electrode into the muscular wall of the LES. Clips are applied to the suture attached to the distal end of the lead to prevent retrograde movement of the electrode. The lead also includes an anchoring member for anchoring the portion of the lead proximal to the electrode. The method and lead used with the method allow the surgeon to work within the confined anatomy present at the gastroesophageal junction and prevents backwards movement and dislodgment of the electrode. The implantation procedure can be combined with a hiatal hernia repair to repair the hernia and prevent recurrence of a hiatal hernia.
