About this trial

This is an interventional treatment trial for Gastroesophageal Reflux Disease focused on measuring GERD

Eligibility Criteria

18 Years - 85 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Age ≥ 18 years, < 85 years, life expectancy > 3yrs.
  • Documented history of GERD symptoms such as heartburn and/or regurgitation.
  • On daily PPI treatment for at least 3-months.
  • Responsive to PPI treatment.
  • GERD symptoms, in absence of PPI therapy (minimum 10 days).
  • Ambulatory Esophageal pH < 4 for ≥ 5% time or pH < 4 for ≥ 3% time in supine position.
  • Patient is a surgical candidate.

5. Study Description

Brief Summary
Magnetic Esophageal Sphincter implant is intended to reinforce Esophageal Sphincter function in the treatment of Gastroesophageal Reflux Disease (GERD)
Detailed Description
The purpose of this feasibility study is to collect preliminary performance and safety information and develop procedural optimization for the Torax Medical Inc. Magnetic Esophageal Sphincter device (MES) in reinforcement of Esophageal Sphincter function to treat Gastroesophageal Reflux Disease (GERD). The information from this study will be used to support the design and conduct of an expanded clinical trial.
