WallFlex® Duodenal Stent

Product Information

Access - Low profile 10Fr TTS/OTW delivery catheter provides support and control of system access and manipulation¹

Placement - Stent visibility and delivery system are engineered to support confidence and control during the procedure

• Radiopaque markers and clear transition zone for positioning and placement accuracy¹
• Recapturing and repositioning of the stent is possible up to approximately 70% deployment¹

System - According to physicians in a European multi-center limited launch, the delivery system and tapered tip support superior access, system trackability and stent deployment, even under highly tortuous anatomies (as compared to competitive products)¹

Stent - Specific mesh design provides excellent stent adaptation to the anatomy, while maintaining lumen integrity¹

• Dedicated flared design offered in a variety of stent diameters and lengths accommodates anatomical needs⁵
• Large diameter stent designs are generally associated with improved obstruction relief and reduced risk of migration^2,3,4,5

Nitinol Construction:

• Complete mesh visibility under fluoroscopy¹
• Patented design with flexibility and radial force to support luminal patency¹
