The inflatable cuff (2) on an endotracheal tube has several annular channels (20, 21) around its outside along a central region of the cuff. The channels (20, 21) have a keyway shape and are produced by applying reinforcing bands (40, 41) to the surface of the cuff (2) so that, when inflated, expansion is restricted in the region of the channels. <IMAGE> |
