ABSTRACT:
A tubular assembly having a plurality of lumens is configured for insertion into the mouth and throat of a patient with a proximal end of the tubular assembly extending from the patient's mouth and a distal end of the tubular assembly extending into the patient's esophagus. The tubular assembly further includes a transition portion near the tubular assembly. The transition portion is configured to transition from a relatively radially large proximal end to a relatively radially small distal end, with the relatively radially small distal end being in communication with at least one of the lumens. The relatively radially large proximal end is configured to abut the aryepiglottic folds of the patient to arrest insertion of the tubular assembly with the relatively radially small distal end of the transition portion extending into the patient's esophagus. A method of providing breathing assist includes inserting the tubular assembly into the mouth and throat of a patient with the relatively radially large proximal end abutting the aryepiglottic folds and the distal end of the transition portion extending into the patient's esophagus.
