Boston Scientific WallFlex Colonic Stents M00565050
The WallFlex Colonic Stent is a single-use, self‑expanding nitinol stent used to relieve malignant colorectal strictures. It features a 25 mm body diameter with 30 mm flared ends, and spans 90 mm to extend through tight lesions. Delivered via a 10 Fr catheter, it’s placed under fluoroscopy and can be repositioned until ~70% deployed.
Designed for palliation or as a bridge to surgery, this stent’s flared ends help maintain luminal patency and minimize migration. Its flexible nitinol mesh conforms to tortuous colon anatomy, with radiopaque visibility for accurate deployment. The delivery system allows recapture up to 70% of deployment, giving clinicians control over placement. MRI‑conditional status ensures safe postoperative imaging under specified conditions .
