Esophageal Stent with Reflux
Control Valve

The EndoMAXX EVT Fully Covered Esophageal Stent with Reflux Control Valve introduces the integration of the latest in esophageal stent and polymer valve technologies. Based on the EndoMAXX Esophageal Stent platform, the integrated reflux control valve is designed to alleviate reflux, a common complication when stenting across the gastroesophageal junction.

Not currently approved or available for sale in the US.


  • The integrated tricuspid valve is designed to mitigate reflux by:
    • Allowing the passage of food and liquids, inverting to permit belching and/or vomiting and reverting back to the standard closed position.
  • The laser cut stent design provides for virtually no foreshortening nor elongation of the stent resulting in:
    • Increased deployment accuracy with no need to compensate for stent foreshortening
    • Reduction in stent movement "inch worming" as a result of the stent elongating and shortening from changes in compression force
  • Proprietary anti-migration struts are designed to reduce stent migration.
  • The exclusive design of the EndoMAXX EVT allows for variations in radial force along the stent body resulting in luminal patency throughout while the soft flared ends are designed to reduce tissue irritation and damage to healthy esophageal mucosa.
  • A proximal metal suture provides a means for repositioning and/or removal of the stent with valve post stent placement.
  • The EndoMAXX EVT is indicated for stenting refractory benign esophageal strictures for up to 6 months.
