Tenax™ Endotracheal Tube
Laser Resistant, Smooth & Flexible

Minimize Damage to Vocal Cords

Engineered to protect and perform, Tenax™ is equipped with an aluminum wrapped, reinforced spiral shaft that runs the length of the tube. Tenax™ is laser resistant, with DualCuffs™ for additional protection against airway fires. Encased in a smooth silicone sheath, Tenax™ helps minimize damage to vocal cords and surrounding anatomy.

Clinical Applications of the Tenax™Laser Resistant Endotracheal Tube

Laser surgery of the airway requires specialized airway management to help protect both the patient and the surgical team. During procedures involving the larynx, vocal folds, trachea and upper airway, the endotracheal tube may be positioned within the laser field, making the selection of an appropriate airway device an important part of the overall laser safety strategy.

The Tenax™ Laser Resistant Endotracheal Tube is intended for endotracheal intubation during surgical procedures involving CO₂ (10.60 μm), KTP (532 nm) and 445 nm Blue Laser systems when endotracheal intubation is required. Its construction combines an aluminum-wrapped shaft, a smooth silicone outer sheath, and a DualCuff™ design to support airway management during laser-assisted procedures. It should always be used in accordance with the Instructions for Use and established laser safety protocols.

Laser Airway Procedures

Laser-resistant endotracheal tubes are commonly selected for surgical procedures in which laser energy is applied close to the airway. Typical applications include:

Laser laryngoscopy
Microlaryngoscopy
Transoral laser microsurgery (TLM)
Vocal cord surgery
Laryngeal surgery
Airway stenosis procedures
Papilloma removal
Head and neck laser surgery
Upper airway reconstruction

These procedures require close coordination between the surgical and anesthesia teams to maintain ventilation while following established laser safety practices.

Airway Fire Prevention

Airway fires remain one of the most serious potential complications of laser airway surgery. Modern laser safety protocols combine the use of an appropriate laser-resistant endotracheal tube, careful oxygen management, close communication between the surgical and anesthesia teams, and adherence to established laser safety guidelines.
The Tenax™ Laser Resistant Endotracheal Tube contributes to this overall safety strategy through its laser-resistant aluminum overwrap, which is intended for use during indicated laser procedures. As with all laser-resistant endotracheal tubes, it should always be used as part of a comprehensive laser safety protocol. The cuffs and the uncovered proximal and distal tube sections are not laser resistant, and direct laser contact with these areas must be avoided.

Frequently Asked Questions

What is the Tenax™ Laser Resistant Endotracheal Tube?

The Tenax™ Laser Resistant Endotracheal Tube is a silicone endotracheal tube intended for endotracheal intubation during surgical procedures involving CO₂, KTP and 445 nm Blue Laser systems. It features a laser-resistant aluminum overwrap, a smooth silicone outer sheath and a DualCuff™ design to support airway management during laser-assisted procedures.
Which procedures commonly require a laser resistant endotracheal tube?

Laser resistant endotracheal tubes are commonly used during procedures in which laser energy is applied close to the airway. These may include laser laryngoscopy, microlaryngoscopy, transoral laser microsurgery (TLM), vocal cord surgery, laryngeal surgery, airway stenosis procedures, papilloma removal, head and neck laser surgery, and other procedures requiring endotracheal intubation.
How does Tenax™ support laser airway safety?

The Tenax™ Laser Resistant Endotracheal Tube provides laser-resistant protection of the tube shaft during indicated laser procedures. Together with careful oxygen management, proper tube positioning, and adherence to established laser safety protocols, it forms one component of a comprehensive airway safety strategy. No laser-resistant endotracheal tube should be considered completely fireproof.
What is the purpose of the DualCuff™ design?

The Tenax™ tube incorporates two fluid-filled cuffs designed to provide an effective tracheal seal. The integrated blue dye indicator system helps identify cuff damage if a cuff is penetrated or ruptured during surgery, allowing the clinical team to respond in accordance with established laser safety protocols.
Why is the Tenax™ tube manufactured with a silicone outer sheath?

The smooth silicone outer sheath is designed to provide a low-trauma surface that helps reduce secretion accumulation while allowing easier insertion and removal. The flexible tube also adapts to changes in airway positioning during surgery.
Which laser systems is Tenax™ indicated for?

The Tenax™ Laser Resistant Endotracheal Tube is indicated for procedures involving CO₂ (10.60 μm), KTP (532 nm) and 445 nm Blue Laser systems when used according to the Instructions for Use. The device should not be used with Nd:YAG lasers, Argon lasers, or other laser types.
Which medical specialists commonly use laser resistant endotracheal tubes?

Laser resistant endotracheal tubes are commonly used by otolaryngologists (ENT surgeons), head and neck surgeons, anesthesiologists, and multidisciplinary airway teams performing laser-assisted procedures involving the upper airway.
