30. A method for blocking a patient'"'"'s esophagus while providing them with an artificial airway, the method comprising the steps of;
-
providing a supraglottic airway capable of creating an airtight seal in the oropharyngeal region of a patient; providing an esophageal blocker; placing said supraglottic airway in a patient in the oropharyngeal region of said patient to provide the patient with an artificial airway; moving said esophageal blocker relative to said supraglottic airway in such a manner that a portion of said esophageal blocker is guided by the structure of said supraglottic airway past said supraglottic airway and into the esophagus of said patient; deploying said esophageal blocker in said esophagus to block said patient'"'"'s esophagus.
