Abstract
A temporary esophagus occlusion device for providing temporary occlusion of the esophagus during intubation of a in patient includes a frame configured to transition between a contracted state, in which it can be swallowed by the patient, and an expanded state, wherein in the expanded state, the frame has a maximum outer diameter sufficient to span an inner diameter of the esophagus of the patient. The device also includes a flexible cover connected to and extending over at least a portion of the frame when the frame is in the expanded state to at least partially block flow of fluid and/or solid materials through the esophagus and a guidewire attached to the frame, sized to be swallowed by the patient along with the frame and having a proximal end portion configured to remain external to the patient's body and a distal end connected to the frame.
