Abstract
A tracheal tube include a conformable conduit that forms a respiratory passage to transfer respiratory gases to a patient. A helical inflatable lumen is formed in or on an interior surface of the conformable conduit. Fluid transferred into the helical inflatable lumen causes the inflatable lumen to assume an expanded configuration to expand an outer diameter of the conformable conduit relative to an unexpanded configuration of the helical inflatable lumen. When in the expanded configuration and inserted in a patient, conformable walls of the conformable conduit expand outwards to contact the tracheal walls such that the conformable conduit is self-sizing to a patient's trachea size.
