Wallflex™ Duodenal Stent

Product Information

Design Development
A commitment to continuous technological improvement in stent design has resulted in the largest diameter stent into a 10F (3.33 mm) Through-the-Scope (TTS) / Over-the-Wire (OTW) delivery system†
 

Nitinol Treatment
Experience with stent materials has enabled creation of a stent in optimal form:
- Complete mesh visibility under fluoroscopy^*1
- Superior radial force in a patented design^*1
 

Access
Low profile 10F (2.22 mm) TTS/OTW delivery catheter provides full support and control of system access and manipulation^*1
 

Placement
Stent visibility and delivery system are engineered to ensure confidence and control during the procedure
- Radiopaque markers and clear transition zone for positioning and   placement accuracy^*1
- Recapturing of the stent and repositioning is possible up to 70% stent   deployment*1
 

System
Braided coaxial system with improved tapered tip provides superior access, system trackability and stent deployment, even under highly tortuous anatomies^*1
 

Stent
Specific mesh design provides excellent stent adaptation to the anatomy, while maintaining lumen integrity*1
- Dedicated flared design in a variety of lengths accommodates anatomical   needs*8
- Large diameter stent design is associated with improved obstruction relief   and reduced risk of migration^*3,4,5
