The Novatech TRACHEOBRONXANE™ DUMON™ Tracheal and Bronchial Stents are the original patented design, used successfully worldwide to treat tracheal obstructions and stenoses. The stents are made from implant-grade silicone suitable for long-term placement and feature an exclusive surface treatment to ensure non-adherence. The material is flexible enough to allow for atraumatic insertion and placement, yet will seek its original shape following placement, providing the force necessary to correct extrinsic compression of the trachea. The patented stud design aids in preventing migration by naturally fixing the stent between the cartilaginous rings of the trachea. The ends of the stents are specially beveled to maximize airflow while helping to prevent crusting and granulation tissue from forming. DUMON™ Stents are available in both clear and radiopaque silicone.
