Abstract

An airway device includes an airway tube having a first end surrounded by a laryngeal cuff which includes a back dorsal portion, a front face portion and a tip portion. The front face portion is shaped to form an anatomical fit over the laryngeal inlet of a patient, and to form a seal with the laryngeal inlet of the patient. The tip portion includes an annular sealing bulge which is adapted to wedge into an upper esophagus region of the patient. The annular sealing bulge improves sealing of the tip of the laryngeal cuff in the upper esophageal region of the patient. The annular sealing bulge is preferably formed from a soft polymeric or other plastics material with a Shore hardness of between 40 and 000 on the A scale, and allows for better sealing with a more variable range of upper esophageal anatomical features.
