Boston Scientific has received Health Canada approval for its WallFlex Biliary RX Fully Covered Stent to treat benign biliary strictures.

The WallFlex Biliary RX fully covered stent is built with a Platinol (platinum-cored Nitinol) wire.

The stent features radial force – which aids in maintaining duct patency and resist migration, flexibility – to aid in conforming to tortuous anatomies and full-length radiopacity – to increase stent visibility under fluoroscopy.

The WallFlex Biliary RX family of stents is available in fully covered, partially covered and uncovered versions.

The covered stents have a silicone polymer Permalume coating designed to reduce the potential for tumor/tissue ingrowth, and an integrated retrieval loop for removing or repositioning the stent.

Boston Scientific Endoscopy Division president David Pierce said with their full line of WallFlex Biliary, Enteral and Esophageal Stents, Boston Scientific offers a range of treatment options to diagnose, palliate and treat patients with gastrointestinal diseases.

In the US, the WallFlex Biliary RX Fully Covered Stent is not approved for the treatment of benign biliary strictures.
