Claim:
A laryngeal mask airway device comprising: A. an inflatable cuff, the cuff defining an anterior side, a posterior side, and a central aperture, the cuff being insertable through a mouth of a patient to an inserted location within the patient when the cuff is deflated, the anterior side of the cuff forming a seal around a laryngeal inlet of the patient when the cuff is inflated and when the cuff is at the inserted location; B. a backplate attached to the cuff, the backplate being attached to the cuff only at locations that are closer to the posterior side of the cuff than to the anterior side of the cuff; and C. an airway tube extending from the backplate to a proximal end, the proximal end of the airway tube being disposed outside the patient's mouth when the cuff is at the inserted location, a continuous airway extending from the proximal end of the airway tube to the central aperture of the cuff.
