    Abstract: A cuffed tracheal tube for use in intubation of a trachea of a patient during laser surgery involving the head or neck of the patient, includes a flexible aluminum conduit, and an expandable cuff carried at one end of the conduit and including a body of sponge-like material enclosed within a cover filled with water which saturates the sponge-like body while expanding the cuff to provide a seal between the tracheal tube and the trachea of the patient. The flexible aluminum conduit and the water saturated cuff define a heat dispersion medium for absorbing laser energy engaging the tracheal tube.
