Tracheobronxane™ Dumon® ST was created in collaboration with Prof. Vergnon (Saint Etienne University Hospital,  France). It is perfectly adapted to

• complex benign stenoses
• post intubation stenoses
• post tracheostomy stenoses
• subglottic stenoses (custom made)

Easy to place after laser resection or dilatation, this stent is designed to avoid the risk of migration inherent to compression development. No migration was observed in a  study covering a follow-up period of two years.1)

The distal and proximal ends correspond to the size of the healthy trachea. The central part is narrower, reducing the risk of traumatising the stenosis while maintaining a sufficient lumen for the airflow and reducing the risk of recurrence.

With a mean duration of 19,6 months a curative effect has been observed in 4 from 13 patients.¹⁾

In some cases, this stent can prevent a tracheostomy.
