Abstract
An endotracheal device comprises an air tube adapted to be inserted through the oral or nasal passage and into the trachea to provide an air passage for respirating a patient. The air tube includes an inflatable cuff mounted at the distal end, and a membrane containing a cushioning material disposed along the air tube adjacent the cuff in a position to prevent direct contact between the air tube and the cricoarytenoid joint and its surrounding tissues.
