A laryngeal mask assembly has a mask portion 13 formed by a flexible bag 16 enclosing a mount 15 attached to the patient end of a tube 1. The bag 16 is sealed to the mount 15 around an opening 22 at the patient end of the tube. The neck 23 of the bag 16 is sealed to the tube 1 rearwardly of an opening 5 from a inflation lumen 2 by which the bag can be inflated to form a cushion 30 on the forward surface of the mount 15. The mount 15 is curved rearwardly around its outer edge 20 and the bag 16 also inflates away from the rear surface of the mount to provide an expandable cushion 31 on the rear of the mount. <IMAGE> |
