Dumon 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, and 16 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 TRACHOBRONXANE® 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 signifi cantly enhances respiratory fl ow. [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).
