BUMPY™ Biliary Stent


  • Benign biliary strictures and pancreatic strictures


  • Irregular cell sizes with different magnitudes of segmental radial force with flared ends
    – Irregular cell sizes of segmental radial force does not completely compress the side branches for preventing stent related pancreatic sepsis or pancreatitis
    – Anti-migration : Both flared ends prevent the risk of migration
  • Easy removal : Fully PTFE (body portion) and silicone (both flared ends) covered design along with a removal string at the proximal end of the stent for easy removal
  • Radiopaque marker : 3(three) at both ends & 2(two) in the middle
