Tracheobronxane™ 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 12, 13, 14, 16, 18 and 20 mm are available with a wall thickness of only 1.0 mm (TF stents).
Features of the TF stents
enhanced respiratory flow
The larger inner diameter of a TF stent significantly enhances respiratory flow. For a standard tracheal stent of 50 mm in length and 16 mm in external diameter, the inner diameter increases by approx. 6%, resulting in an increase of the luminal volume of 16%. Due to the enhanced respiratory flow the patient’s condition is improved considerably.
improved mucociliary clearance
The enhanced flexibility due to the thinner walls of TF stents facilitates the internal movements of the trachea (respiration, ease of the peristaltic movements of the esophagus). This dynamic stent concept allows better mucociliary clearance (depending on mucous viscosity).
