Niti-S Bronchial Comvi™ (Triple Layer, Covered) Stent

Comvi™ (Triple Layer, Covered)

Category: Bronchial Stents  

Available in Tracheal and Bronchial sizes. 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.


Malignant and benign tracheobronchial obstruction


  • Triple layered construction: Biocompatible PTFE membrane tube is held between inner and outer mesh
  • Retrieval string at the proximal end: reposition or removal of stent
  • Radiopaque marker: 4 (four) at both ends and 4 (four) at the middle
  • Unfixed cell structure enables stent to conform to tortuous anatomy
  • Outer wire mesh reduces the risk of migration
