Abstract
An airway device 64 includes a hollow tube 51 having a proximal end 65b and a distal end 71, and is formed with a straight section 65 and a curved section 68. The tube 51 can include a proximal portion 65a, which extends from the proximal end 65b for receipt of a face mask 180. When the airway device 64 is placed in a patient's mouth 28, oral cavity 34 and oropharyngeal area 36, the distal end 71 is located at the patient's glottic opening 46 and vocal cords 40. Inflatable cuffs 75, 73 and 73a may be located individually on the tube 51 in selectable single, double and triple cuff embodiments to form seals in the areas of the patient's mouth 28, oral cavity 34, oropharyngeal area 36, glottic opening 46 and vocal cords 40, esophageal opening 48 and inner nasal-passage opening 33.
