Abstract
A laryngeal mask airway has a foam cuff formed on the patient surface of a plate attached at the patient end of a tube. The cuff is of a self-skinning foam so that the skin of the foam forms the outer surface of the cuff and seals with the plate. An air lumen extruded along the tube opens at one end into the interior of the cuff and at the other end connects with an air line. The cuff can be compressed for insertion and removal by applying suction to the air line.
