Patent ID: 8449713

Claim:
A method of making a device including: (A) providing an inflatable mask comprising a relatively stiff component and a relatively soft compliant flexible component, the mask being insertable, at least when deflated, through a mouth of a patient to an inserted location within the patient, the inserted location being near a laryngeal inlet of the patient; (B) providing an airway tube coupled to the mask, the airway tube extending from a proximal end located outside of the patient's mouth through an interdental gap to the mask when the mask is at the inserted location, the interdental gap being a space between the patient's lower teeth and the patient's upper teeth; (C) providing an evacuation tube for communication with an esophageal inlet of the patient, the evacuation tube being coupled to the mask, the evacuation tube extending from a proximal end located outside of the patient's mouth through the interdental gap to the mask when the mask is at the inserted location; and integrally forming the relatively soft compliant flexible component of the mask in a single moulding operation; wherein integrally forming the relatively soft compliant flexible component of the mask comprises integrally forming an inflation-air inlet formation, an outwardly directed distal-end tube and an open skirt.
