Embodiment Construction

[0045]Referring now to the drawings, there is illustrated a laryngeal mask airway device 1 for insertion into a patient to provide an airway passage to the patient's glottic opening, the device 1 comprising an airway tube 2, a mask 3 attached to the airway tube 2, the mask 3 comprising a body 4 having a distal end 5 and a proximal end 6, a peripheral inflatable cuff 7, and defining an outlet 8 for gas, the mask 3 being connected to the airway tube 2 for gaseous communication between the tube 2 and the mask, the distal end of the mask being ventrally displaced, relative to the proximal end.

[0046]In this embodiment the device 1 further comprises an oesophageal drain 10, the drain 10 comprising a conduit 11 extending from an opening 12 at the distal end 5 to a drain outlet 13 disposed to the outside of the patient when the device 1 is in place, wherein the conduit 11 is formed integrally in the material of the body 4.

[0047]As can be seen from the drawings, the device 1, in terms of ove...
