Umbrella Valve Stent

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. 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.
