Biliary NAGI Pseudocyst drainage Stent

NAGI™ Stent (Pseudocyst drainage)

Category: Biliary Stents  

The Niti-S Nagi™ Stent consists of an implantable metallic stent and an introducer system. The stent is made of Nitinol wire. It is a flexible, fine mesh tubular prosthesis which has radiopaque markers on each end and at the center. The Stent is loaded in the introducer system and upon deployment the body of the stent imparts an outward radial force while both heads impart a horizontal inward force, allowing transmural drainage. Niti-S Nagi™ Stent is Fully Silicone Covered and can be removed; (see Warnings).

Details / Features

  • Wide and smooth flare edges
  • Prevent the risk of migration and possibility of stent related luminal damages
  • Available in various diameters (Up to 16mm)
  • Optimize drainage and provide large enough path for following necrosectomy if required
  • Retrieval String for repositioning or easy removal
  • Radiopaque Markers: 3(three) at both ends & 2(two) in the middle
