An endotracheal tube 10 comprising an expandable hinge portion 13,14, wherein the expandable hinge portion 13,14 is flexible when expanded, and substantially rigid when contracted. The expandable hinge portion 13,14 is expanded upon insertion of a rod 30 e.g. endoscope. The tube 10 further comprises at least one control wire 17 which can cause deflection of the tube 10 and compress the tube 10 by compressing the hinge 13,14. In another aspect, an endoscope comprises a flange 31 for cooperation with a distal portion 21 of an endotracheal tube 10, and a connector portion 31c for cooperation with a proximal portion 21 of the endotracheal tube 10. |
