AbstractThere is disclosed an endotracheal tube which is collapsed transverse to the longitudinal dimension of the tube for insertion into the trachea of a patient. After the tube is in place, it is expanded to open an unobstructed passageway therethrough. An expandable cuff is provided on the exterior of the tube to afford a seal between the trachea and the tube. The same techniques are applicable to urethral catheters.
