Boston Scientific WallFlex Biliary RX Stents M00570490
The WallFlex™ Biliary RX Fully Covered Stent is a single-use, laser-cut nitinol stent featuring a 10 mm diameter and 80 mm length, delivered through an 8.5 Fr (≈ 2.83 mm) catheter. It is fully covered with Permalume™ coating to help resist tissue ingrowth and prevent migration. Designed for malignant and benign biliary strictures, it’s retrievable using the integrated retrieval loop.
Engineered to minimize foreshortening and improve placement accuracy, this fully covered stent includes flared, looped ends that resist migration and reduce tissue trauma. The Permalume™ covering forms a smooth barrier against tumor in-growth, while the single-catheter, reconstrainable delivery system (up to 80%) enables precise deployment under fluoroscopy. Built on flexible Platinol™ wire, the stent accommodates placement through tortuous anatomy and provides durable radial force to maintain patency. Fully covered variants are removable for up to 12 months post-placement in benign biliary strictures and are MRI-conditional at 1.5 T/3 T.
