  • Patent number: 5499625
    Abstract: An airway for both sole esophageal obturator ventilation and for combined endotracheal and esophageal obturator ventilation of a patient. The airway has two lumens one of which has an open distal end and the other of which has a closed distal end. The airway further has an inflatable distal cuff and an inflatable pharyngeal cuff. Communicating with the lumen having the closed distal end is at least one air outlet located in the airway wall between the two inflatable cuffs. To determine the position and orientation of the airway within a patient, the airway is provided with an X-ray opaque stripe that preferably axially extends in the wall, but is interrupted by at least one air outlet between the inflatable cuffs. An X-ray opaque shaft may also be present between the inflatable cuffs and is preferably attached to the wall. The airway may also be provided with monitoring lumens and deflector means in communication with the lumen that has the open distal end.
