With the Umbrella-Valve-Stent, MICRO-TECH combines perfect hold with effective protection against reflux. Its innovative design prevents stent migration and avoids development of pressure necrosis in the stomach. For even greater patient comfort, the stent is also equipped with the unique 2-way valve system from MICRO-TECH. Liquids and foods reach the stomach unimpeded through the valve system and reflux is dramatically prevented. In the event of excessive pressure, the valve opens towards the oral direction allowing the patient to vomit.

TOP FORM DESIGN
The unique umbrella design prevents migration of the stent in the oral and gastric directions. The stents’ adaptability in the area of the cardia eliminates the possiblility of protruding into the stomach, which in turn prevents development of pressure necrosis to a great extent.
