COMVI™ Pyloric/duodenal Stent


  • Malignant gastric outlet obstruction


  • Triple layered construction : A biocompatible PTFE membrane tube is held between the inner and outer mesh

– An 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 migrations

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