Tracheobronxane™ Dumon® TD / TF
- TD / TF
Endotracheal Tracheobronxane™ Dumon® stents are available with two wall thicknesses. The TD stents have a wall thickness of 1.5 mm. Additionally, endotracheal stents of 13, 14, 16, 18 and 20 mm are available with a wall thickness of only 1.0 mm (TF stents).
Clinical results obtained with Y stents and other bronchial stents* show that no secondary compression has been observed with Tracheobronxane™ Dumon® silicone stents.
Due to the special material and shape of Tracheobronxane™ Dumon® stents, the centripetal force is not altered, even with a wall thickness of only 1.0 mm, allowing increased airflow and better mucociliary clearance.

Features of the TF stents
- enhanced respiratory flow
The larger inner diameter significantly enhances respiratory flow. [For a standard tracheal stent of 50 mm in length and 16 mm in external diameter the luminal volume increase is 16% while the inner diameter increases by approx. 6%.]
- improved mucocilar clearance
The thinner walls facilitate the internal movements of the trachea (respiration and swallowing). This dynamic stent concept allows better mucocilar clearance (depending on mucous viscosity).
