Abstract:
1. An apparatus comprising: a tubular assembly comprising a plurality of lumens, the tubular assembly being 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 comprising a transition portion near the distal end of the tubular assembly, the transition portion comprising an outer wall defining at least in part a chamber corresponding to each lumen, the outer wall of the transition portion being configured to transition from a relatively radially large proximal end to a relatively radially small distal end, the relatively radially small distal end being in communication with at least one of the lumens, the relatively radially large proximal end being 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.
