An expandable endotracheal tube and the like comprising extended, spaced segments. Actuating members fill the spaces between adjacent segments. The actuating members and the segments have curved edges so that sliding movement of the actuating members will cause the circumference of the tube to expand. A syringe type of device at the proximal end of the tube causes the actuating members to slide and effect the expansion of the segments.
