Product Information

Building on the best of Boston Scientific’s industry-leading stents, the WallFlex Stent seeks to deliver luminal patency through a combination of flexibility and control to support your goal of optimized patient care.

Stent-Related Features

• Proprietary Permalume® Silicone Covering: The Permalume Silicone Covering is designed to help reduce food impaction, prevent tumor ingrowth and seal concurrent esophageal fistulas.
• Proximal and Distal Flared Ends:The progressive step flared ends may reduce the risk of stent migration.
• MRI Conditional: Non-clinical testing has demonstrated that the WallFlex Partially Covered Esophageal Stent is MR Conditional. It can be scanned safely under the conditions outlined in the Directions for Use.

Delivery System-Related Features

• Flexible: The flexible delivery catheter is designed to enhance the ease of intubation and navigation through the esophagus.
• Endoscopic Transition Zone: The Yellow Transition Zone is designed to increase stent placement accuracy when the stent is deployed using endoscopic visualization.

Device Highlights

• 1:1 Coaxial Stent Deployment: The coaxial delivery system is designed to result in 1:1 stent deployment. When the distal handle is pulled towards the proximal handle, the amount of stent released corresponds to the distance pulled.
• Low Profile: The 18.5 French, low profile delivery system is designed to traverse tight strictures.
• Flexible Braided Construction: The multiple wire braided construction is engineered to allow the stent to adjust to forces from the esophageal anatomy such as peristalsis and strictures.
• Thick Nitinol Wires¹: The thick nitinol wires provide radiopacity to facilitate stent placement.
• Removal Suture (Teflon® Coated Polyester): The removal suture facilitates stent removal during the initial stent placement procedure.
  The polyester is designed to make the suture strong and flexible while the Teflon coating is designed to be lubricious, potentially reducing frictional force when pulled through other materials.
