Background & Unmet Need

  • Gastroesophageal reflux disease (GERD), a condition in which stomach acid enters the esophagus, affects over 40 M Americans annually
  • Significant discomfort and/or damage can be caused, as cells on the lining of the esophagus are not resistant to stomach acid
  • Some patients do not respond to medications or become refractory and require surgical intervention
  • However, current diagnostic tests to assess reflux are inadequate, as many patients do not present with classical symptoms
  • It is therefore difficult to predict which patients while experience symptom resolution after surgical intervention
  • Unmet Need: Improved methods of diagnosing GERD to identify patients who may benefit from surgical intervention

Technology Overview

  • The Technology: A temporary, endoscopically-placed device that mimics surgery by artificially recreating a normal lower esophageal sphincter
  • The device spans the gastroesophageal junction, and includes an inset two-way valve that allows food to pass but prevents reflux of stomach contents
  • After placement of the device, patients may be monitored for up to 30 days to assess impact on symptoms
  • Successful symptom resolution increases confidence in a GERD diagnosis and indicates that a patient is likely to respond to therapeutic or surgical intervention

Technology Applications

  • Temporary device for definitive diagnosis of GERD
  • Identification of patients who may benefit from additional therapeutic or surgical interventions
  • Semi-permanent stents for long-term management of GERD symptoms

Technology Advantages

  • Temporary device that may be placed with an endoscope
  • Provides a physical barrier to evaluate the need for surgical
  • Pressure required to open the valve in the retrograde is sufficient to prevent reflux but still allows for belching and vomiting
