Abstract
An expandable endotracheal tube and the like comprising a pair of overlapping extended segments. A piston drive mechanism actuated by air under pressure is disposed between the segments to effect the expansion of the tube in situ. Slidable dovetail joints insure that the segments slide only circumferentially with respect to each other. In another embodiment, the two segments are fused along one overlapping edge and a pair of catheters extend circumferentially with one entering the other.
