Kaffes™ Stent

Category: Interventional Biliary Stents  

To treat anastomic strictures after liver transplantation


Anastomic strictures after liver transplantation

Details / Features

  • Characteristic waist at mid-portion of the stent: Waist shape of the stent allows strong radial force and preventing migration
  • Short length of stent: Using a short stent across the stricture prevents to impart pressure over a large area of normal duct by reducing the potential risk of necrosis and fibrosis
  • Long platinum radio-paqued retrieval string: The long platinum string helps easy removal from the high up location of CBD
  • Covered part can prevent bile leak through transluminal track between stomach and left hepatic duct.
  • Uncovered part can prevent migration and cholangitis without obstructing side branches of hepatic ducts.
  • Flared end is located out of the stomach wall preventing migration into hepatic duct

Radiopaque Markers: Three (3) at both ends and two (2) in the middle
