Boston Scientific Ultraflex Tracheobronchial Stents M00576650
The Ultraflex Tracheobronchial Covered Stent is a sterile, single-use, partially covered nitinol airway stent with an 18 mm expanded diameter and 60 mm length. Its midsection features a 45 mm silicone covering to resist tumor ingrowth, with uncovered ends to maintain mucociliary clearance. Delivered via a low-profile, distal-release catheter with radiopaque markers for precise bronchoscopic and fluoroscopic placement.
This self-expanding stent’s knitted nitinol design provides consistent radial support to maintain airway patency while balancing coverage for tumor resistance and natural clearance at its ends. A 45 mm central silicone sleeve helps inhibit tumor ingrowth, improving long-term lumen openness. The distal-release catheter and radiopaque markers enable controlled deployment under bronchoscopic and fluoroscopic guidance. Compatible with a 0.035″ Jagwire pulmonary guidewire and deployable via flexible or rigid bronchoscopy in a single-use format.
