Abstract: An endotracheal tube 10 has an inflatable bag 20 towards its patient end for sealing with the inside of the trachea 11. Additionally, the tube 10 has a second, longer bag 50 separately inflatable to a lower pressure than the first bag 20 and such as to extend along the tube 10 from the first bag 20 to and through the vocal chords and larynx 13 and occupy the space between the first bag and the vocal chords 13. The inflated second tube 50 can thus reduce passage of secretions and minimizes the space available for them. A suction line 48 extends along the tube, opening between, or at the interface between, the two bags 20 and 50 so that any body secretions that do pass the second bag can be removed.
