METHOD FOR AN ENDOSCOPIC AIRWAY DEVICE

Abstract

An airway device includes an outertube and a scope channel partially enclosed by the outertube. An intraluminal space in the outertube, not occupied by the scope channel, provides a passageway for air flow to the patient. An esophageal cuff is positioned distally on the scope channel. When inflated, the esophageal cuff secures the airway device in the proximal esophagus of the patient and helps to prevent gastric reflux by mechanically blocking gastric content from entering into the larynx. An inflatable bladder is attached to an anterior surface of the scope channel between the esophageal cuff and a distal opening of the outertube. When inflated, the bladder forms a tubular ring that pushes against the epiglottis and/or other soft tissue towards a wall of the hypopharynx to produce an unhindered air passage into the patient's trachea.
