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 24-72hrs.

Tissue InGrowth 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.

Removability & Adjustability
The 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.

Delivery System Details

Pre-dilation Avoidance
The 18.5 French (6.2mm), low profile delivery system is designed to traverse tight strictures.*

Endoscopic Placement
The Endoscopic Transition Zone is designed to aid in stent placement accuracy when deployed using endoscopic visualization.

Stent Placement Accuracy
The coaxial delivery system is designed to result in 1:1 stent deployment.

The fully covered stent may be reconstrained up to 75% of deployment and 2 times during the initial stent placement procedure.**

* Predilation may not be required, depending on stricture lumen diameter.
** A stent can not be reconstrained after the reconstrainment limit has been exceeded.
