    Comvi™ Tracheal (Triple Layer, Uncovered)

    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
