Niti-S Biliary Interventional Comvi Covered

Colonic Comvi™ Stent

Category: Biliary Stents  

Irregular cell sizes allow for segmental radial force so side branches of pancreatic duct are not compressed, thus reducing stent related pancreatitis or pancreatic sepsis. Both flared ends reduce risk of migration. Fully PTFE body cover and silicone flare cover along with a removal string at proximal end allow for easy removal. Radiopaque markers: 3 (three) each end & 2 (two) in the middle.

Indication

Malignant colorectal obstruction

Details / Features

  • Triple layered construction: Biocompatible PTFE membrane tube is held between inner and outer mesh
  • Unfixed cell structure enables stent to conform to tortuous anatomy
  • PTFE membrane prevents the risk of tissue invasion
  • Outer wire mesh prevents the risk of migration
  • Minimum foreshortening for accurate stent placement
  • Radiopaque marker: 4(four) at both covered part ends
