The disclosed laryngeal mask airway device includes a rigid airway tube, a mask portion, and a viewing system. The mask portion is inflatable and can be inserted, when deflated, through a patient's mouth to a location near the patient's glottic opening. The mask portion also includes an epiglottis elevator bar and a distal end of the bar defines an aperture. The viewing system has a proximal end located outside the patient. The viewing system also has a distal end positioned so that light rays can pass from a portion of the patient's anatomy, through the aperture in the elevator bar, and into the distal end of the viewing system. |
