COMVI™ Biliary Stent


  • Malignant biliary strictures


  • Triple layered construction : Biocompatible PTFE membrane tube is held between the inner and outer mesh
    – The unfixed cell structure enables the stent to conform to tortuous anatomy
    – The PTFE membrane prevents the risk of tissue invasion
    – The outer wire mesh prevents the risk of migration

  • Minimum foreshortening for accurate stent placement
  • Radiopaque marker : 4(four) at both covered part ends
