WallFlex Esophageal Stent Details

Migration Resistance
The Progressive Step Flared Ends may assist in anchoring the stent within the esophageal lumen.

Stricture Resolution
The multiple wire braided construction is engineered to allow the WallFlex Esophageal Stent to adjust to forces from the esophageal anatomy such as strictures and peristalsis. The design allows for gradual stent expansion, which is typically complete after 24-72 hrs.

Tissue In-Growth Prevention
The Permalume™ Silicone Covering extends the entire length of the WallFlex Esophageal Stent in the fully covered version and is designed to prevent tumor ingrowth as well as stent concurrent esophageal fistulas and help reduce food impaction.

Adjustability
The Teflon™ Coated Polyester Removal Suture facilitates removal during the initial stent placement procedure.

Fluoroscopic Visualization
The Nitinol construction allows for clear visualization during fluoroscopy, ensuring accurate stent placement.
