Boston Scientific Ultraflex Tracheobronchial Stents M00576690
The Ultraflex Tracheobronchial Stent is a sterile, single-use, partially covered nitinol airway stent with a 20 mm expanded diameter and 80 mm length. It features a 65 mm silicone-covered midsection to prevent tumor ingrowth and uncovered ends to promote mucociliary clearance. It’s deployed via a low-profile distal-release catheter with radiopaque markers—compatible with 0.035″ pulmonary guidewires.
This self-expanding knitted nitinol stent delivers steady radial force to maintain airway patency in patients with malignant obstructions. The 65 mm silicone-covered midsection resists tumor ingrowth while uncovered ends encourage tissue integration and mucus clearance. Its distal-release delivery method, assisted by radiopaque markers, allows precise bronchoscopic and fluoroscopic placement. Supplied on a 95 cm working-length catheter for flexible or rigid bronchoscopy.
