Boston Scientific Ultraflex Tracheobronchial Stents M00576670
The Ultraflex Tracheobronchial Stent is a sterile, single-use, partially covered nitinol airway stent with a 20 mm expanded diameter and 40 mm length, featuring a 25 mm silicone-covered midsection. It is deployed using a distal-release catheter over a 0.035″ pulmonary Jagwire and includes radiopaque markers for precise bronchoscopy placement. Designed to relieve malignant airway strictures while promoting mucus clearance at the uncovered ends.
This self-expanding knitted nitinol stent delivers steady radial force to support airway patency and resist dynamic compression. The 25 mm silicone-covered segment in the center prevents tumor ingrowth, while uncovered ends allow mucociliary clearance and tissue integration. Its distal-release system with radiopaque markers ensures accurate placement under fluoroscopic or bronchoscopic visualization. Delivered via a 95 cm low-profile catheter compatible with standard pulmonary guidewires for flexible or rigid bronchoscopic use.
