DUMON™ ST were designed in collaboration with Prof. Vergnon (Saint Etienne University Hospital, France). They are especially adapted to
- complex benign stenoses
- post intubation stenoses
- post tracheostomy stenoses
- subglottic stenoses.
Easy to place after laser resection or dilatation, this stent is designed to avoid the risk of migration inherent to compression reduction. No migration was observed in a study covering a follow-up period of two years. With a mean dwell time of 19.6 months, even a curative effect has been observed in 4 of 13 patients.1)
The diameters of the distal and proximal ends correspond to the size of the healthy trachea. The central part is narrower, reducing the risk of traumatizing the stenotic part of the trachea while maintaining a sufficient lumen for the airflow and thus reducing the risk of restenosis.
The ST was developed in cooperation with Prof. Vergnon, France, especially for treatment of benign tracheal stenosis such as post-intubation stenosis in the proximal part of the trachea. In some cases, placement of an ST-Stent can help prevent a tracheostomy.2)
