Original DUMON®

Silicone Airway Stents

Tried and tested for decades

Since 1989, Novatech has been offering the patented DUMON® stents - a stent system that has proven itself as a reference product for improving patient comfort in airway stenosis.

DUMON® stents are made of specially treated transparent or radiopaque medical grade silicone (implantable for more than 29 days). They are considered to be the gold standard with which all other stents should be compared.1,2

Since 2011, an optimised line of the original DUMON® stent is available: NOVATECH® GSS™ feature studs filled with gold and barium sulphate. They combine good x-ray visibility with an optimised endoscopic vision of the tissue.

DUMON® stents are manufactured from unrestrictedly implantable silicone and are very well tolerated by the airway mucosa. DUMON® stents are supplied sterile and ready-to-use.
