COMVI™ Biliary Stent

Category: Gastroenterology  

A triple layered unfixed cell stent provides the ideal combination of radial and axial force to maintain full lumen patency in tortuous anatomies. Available in fully covered or bare ends. Bio-compatible PTFE membrane tube is held between inner and outer mesh.

Details / Features

  • Unfixed cell structure enables stent to conform to tortuous anatomy
  • PTFE membrane prevents the risk of tissue ingrowth
  • Outer wire mesh reduces the risk of migration
  • Minimum foreshortening for accurate placement

Indication: for malignant biliary strictures.

Radiopaque markers: 4 (four) at each end
