DUMON™ Y stents have 3 rows of studs. The posterior side has no studs in order to avoid trauma of the tracheo-esophageal wall. The branches are angled according to anatomy.
Custom lengths and diameters are available on request. DUMON™ Y stents may be modified by Novatech in order to allow airflow to the right upper lobe.

A closed right branch stem for pneumonectomized patients with a fistula is available on a custom basis.
