Interventional Radiology Biliary D-Type Uncovered

D-Type™ Uncovered Stent

Category: Interventional 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.
