Abstract
A laryngeal mask assembly has a mask portion formed by a flexible bag enclosing a mount attached to the patient end of a tube. The bag is sealed to the mount around an opening at the patient end of the tube. The neck of the bag is sealed to the tube rearwardly of an opening from a inflation lumen by which the bag can be inflated to form a cushion on the forward surface of the mount. The mount is curved rearwardly around its outer edge and the bag also inflates away from the rear surface of the mount to provide an expandable cushion on the rear of the mount.
