Oral endotracheal tube Tenax®

adult

Product overview
The Tenax® laser resistant endotracheal tube features an aluminum-wrapped, reinforced spiral shaft to prevent airway fire. Tenax® is latex-free and encased in a smooth sheath of flexible silicone to minimize damage to vocal folds and related anatomy. The device was created by clinical experts to reduce trauma to the airway and to provide enhanced protection during laser laryngeal and airway procedures.

Clinical context & risk
Three essential components are needed to initiate and sustain a fire during medical procedures in a patient‘s airway: oxygen + CO2 laser + endotracheal tube. Of recorded surgical fires in otolaryngology, 36% occurred during tracheotomy and 25% under endoscopic laryngotracheal procedures. Complications of airway fires may range from unexpected mechanical ventilation to death in extreme cases.

DualCuff™ & blue dye
The Tenax® DualCuff™ offers an extra layer of protection with two sealing points, reducing the chance that the cuff or tube will be compromised by stray laser energy. The cuff system is preloaded with a biocompatible blue dye that alerts the surgeon if a cuff is inadvertently violated.

Performance & user feedback
Over 92% of surgeons (DayUser observation 2025 / retrospective data analysis in the US market) rated Tenax® as excellent in helping to reduce the risk of airway fires during procedures. Over 98% of surgeons would recommend Tenax® under laser surgery; 98% rated the softness/flexibility and the smooth surface as excellent or good in minimizing inadvertent tissue trauma.

Key indications
Indicated for all types of surgical procedures involving carbon dioxide laser (10.60 µm), KTP laser (532 nm) or Blue Laser (445 nm) (normal pulsed or continuous beam delivery in non-contact mode), when endotracheal intubation is required to administer anesthetic gases or to overcome emergency airway obstruction.

Included with product
Each Tenax® laser resistant endotracheal tube comes with a stylet.
