Abstract
A laryngeal mask including a dome and an airway tube extending from a proximal passage through the dome. The dome has a periphery about its base including at least one receptacle. An inflatable cuff of flexible material has a first longitudinal edge and a second longitudinal edge. The longitudinal edges are joined to form a tube forming the cuff. The cuff substantially encircles the periphery of the dome. The mask has at least one buttress adjacent to the periphery at a distal portion of the dome. The tube is fused adjacent the buttress of the dome, and the fusing is below a posterior surface of the dome wherein, upon deflation of the cuff, the buttress upturns the cuff to facilitate insertion of the laryngeal mask into a patient.
