The Shiley 86402 Laser Oral Tracheal Tube (cuffless, 4.0 mm I.D.) is designed specifically for airway management in surgeries involving lasers (e.g. laryngeal, vocal cord, or tracheal laser procedures). Its stainless steel, spiral-wound construction is engineered to be laser resistant and non-flammable, helping to protect against perforation or ignition if the tube shaft is incidentally struck by a CO₂, KTP, or other surgical laser beam. The spiral steel acts as an airtight structural core and helps prevent longitudinal leaks along the length of the tube, which is a risk in polymer tubes under laser exposure.

In surgical use, this tube is inserted orally (or via the Magill technique) and used as the airway conduit during ventilation. Because it is cuffless, it relies on the natural airway around the tube for sealing (not suitable for high positive pressure ventilation in all cases). The 4.0 mm diameter makes it suitable for small-to-moderate airway sizes—commonly pediatric or sub‑adult patients in laser airway surgery where a laser-safe tube is needed without bulky insulation. Its 6.1 mm O.D. gives some additional structural robustness. The inclusion of a Murphy eye helps maintain distal airflow if the tip abuts tissue or is occluded.

From a procedural perspective, this tube lets surgeons combine ventilation and airway access with laser safety. The use of a laser-resistant tube lowers the risk of fire or tube damage during laser activation. Because it is a specialized, single-use device, it minimizes the need for sterilization and reduces cross-contamination. However, its cuffless nature means clinicians must manage ventilation pressures carefully, and ensure the airway remains sealed or supplemented (e.g. by throat packing, controlled ventilation, or monitoring leak). Proper tube sizing, placement, and checking alignment with the surgical field are critical for safe and effective use in laser airway procedures.
