Tenax® - Laser Resistant Endotracheal Tube

Enhance protection against airway fires and maximize patient safety with Tenax®

The Tenax® laser resistant endotracheal tube has an aluminum wrapped, reinforced spiral shaft to prevent airway fire.
Latex-free, Tenax® is encased in a smooth sheath of flexible silicone, minimizing damage to vocal folds and related anatomy.

Risk of surgical fires in laser laryngeal surgeries


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 the recorded surgical fires in otolaryngology,
· 36 % occurred during Tracheotomy and
· 25 % under endoscopic laryngotracheal procedures.¹


Complications of airway fires can be severe, from required unexpected
mechanical ventilation to death in the worst case.

Tenax - extra layer of protection

The Tenax® DualCuff™ adds protection against airway fires during laser surgery procedures by providing two sealing points and reducing the chance that the cuff or tube will be compromised by stray laser energy.

blue dye alerts

The blue dye alerts the surgeon when a cuff is inadvertently violated.

Over 92 %² of surgeons rated Tenax® as excellent in helping
to reduce the risk of airway fires during the procedure.

Tenax® was created by clinical experts to reduce trauma to the airway

Over 98%³ of surgeons would recommend their peers to use Tenax® under laser surgery

Addressing the preferences for Physical Attributes of Laser-Protected Endotracheal Tubes⁴, Tenax® reduces the risk of tissue trauma during intubation, intraoperative use, and extubation. 98% of surgeons² rated the softness and flexibility of Tenax® as excellent or good in minimizing inadvertent tissue trauma, and 98% of surgeons² value the smooth surface of the tube.

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

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

  • Preformed Tube
    Curved tube conforms to shape of airway; adds flexibility.
  • Smooth Outer Sheath
    Encased in a smooth sheath of silicone, minimizing damage to vocal cords and related anatomy.
  • Preloaded with Blue Dye
    If cuffs are violated, the blue dye alerts the surgeon.
  • Cuffs Tight to Shaft
    The slimmer profile of the Tenax® cuffs sets a new standard.
  • Two Cuffs
    Tenax® DualCuff™ offers an extra layer of protection.
