Wireless charged lower esophageal sphincter stimulator

Abstract

Clinical studies [1, 2] have demonstrated that electrical stimulation of the lower esophageal sphincter (LES) can significantly improve the quality of life of patients with gastroesophageal reflux disease (GERD) and low tone of the LES. Commercially available implantable stimulators like EndoStim® or Enterra®, Medtronic have sizes about 50 x 60 x 10 mm, are powered by non-rechargeable batteries and their implantation requires surgery under general anesthesia. Battery life is usually ≤ 5 years.
