Abstract: A laryngeal airway device (10), having an airway tube (100) which has an internal passage (102) in the airway tube wall for receiving a cuff inflation line (400), and a dome (300) having an inlet and an outlet, where the dome is connected at its inlet with the distal end of the airway tube. The device also includes an annular spoon-shaped inflatable cuff (200) connected with the periphery of the outlet of the dome; a cuff inflation line configured to be in fluid communication with the internal space of the cuff; and a multi-lobed aperture (302) formed in the dome. The aperture is configured to be in fluid communication with the proximal end of the airway tube. The dome has protrusions forming the multi-lobed aperture, such that a flap is configured to prevent the obstruction of the aperture by a patient's epiglottis when the device is inserted into the patient.
