Tracheobronxane™ Dumon®
Tracheobronxane™ Dumon® stents are made of specially treated medical grade transparent or radiopaque silicone without reinforcement (implantable for more than 29 days). They are considered the “golden standard to which all others should be compared”.1)
Depending on design, there are 2, 3 or 4 lines of studs on the stent outside. This stud system has proven its reliability for improved stent fixation between the cartilaginous rings of the trachea and the bronchial tree.
The stent inside is treated with a silicone-based layer which makes the surface anti-adherent, minimizing the risk of obstructions and improving mucociliary clearance.
For the various indications and their sites, a large variety of stent types is available as well as a large choice of lengths and diameters.

Indications
Maintaining airway patency after desobstruction or dilatation of a stenosis, in particular in the following cases:
- tracheobronchial tumors
- tracheal stenoses with scarring
- bronchial stenoses following surgical resection and anastomosis
- bronchial stenoses following pulmonary transplantation
- generally, in any case of reduction of airway diameter due to intrinsic or extrinsic compression.
Features
Perfect adaption
Perfect adaption
The key condition for perfect tolerance of the stents is to use a stent which is perfectly adapted to the patient’s needs. For this reason and in order to be prepared for any situation, it is essential to provide the physician with a basic line of different stent types, diameters and lengths.
The stents must not be cut in order to avoid the risk of granulation and to ensure mucociliary clearance (please refer to the Instructions for Use).
Anti-migration stud system
Anti-migration stud system
The stud design minimizes the risk of migration of the Tracheobronxane™ Dumon® by fixing it between the cartilaginous rings of the tracheo-bronchial tree. The stent design inhibits cough reflexes. The studs reduce direct contact between the stent surface and the mucosa and distribute compressive forces evenly among the small stud surfaces.
Anti-adherent smooth surface
Bevelled ends
Removability
Application
- Placement and removal with a rigid bronchoscope. Novatech advises the use of the
Tonn / Novatech applicator to safely place Dumon® Stents.
