Product Details

WallFlex Esophageal Details

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 optimised patient care.

The WallFlex Oesophageal Stent is available in fully and partially covered options and a variety of lengths and widths.

WallFlex Oesophageal Stent Details

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

Stricture Resolution
The multiple wire braided construction is engineered to allow the WallFlex Oesophageal Stent to adjust to forces from the oesophageal 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 Oesophageal Stent in the fully covered version and is designed to prevent tumour ingrowth as well as stent concurrent oesophageal fistulas.

Removability & Adjustability
The Coated Polyester Removal Suture facilitates removal during the initial stent placement procedure.

Fluoroscopic Visualization
The Nitinol construction allows for clear visualisation 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 visualisation.

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 cannot be reconstrained after the reconstrainment limit has been exceeded.

Clinical Information

Study results found that placement of a WallFlex Fully Covered Oesophageal Stent resulted in safe and effective palliation of malignant dysphagia

Dr. Allesandro Repici et al. authored the largest study on the WallFlex Fully Covered Esophageal Stent, which was published in the December 2014 issue of Digestive and Liver Disease Journal. The goal of the study was to assess the clinical (recurrent dysphagia) and technical success using the WallFlex Fully Covered Oesophageal Stent in patients with dysphagia due to primary inoperable oesophageal cancer.

The study found that placement of a WallFlex Fully Covered Esophageal Stent resulted in safe and effective palliation of malignant dysphagia. The median dysphagia scores improved from “3” (ability to swallow liquids only) to “1” (ability to eat some solid food) at both fourteen days and four weeks after stent placement. In addition, twenty-four of the eighty-two patients (29.2%) went on to receive chemo and/or radiotherapy after stent placement.
