Perilaryngeal oral airway with multi-lumen esophogeal-obturator
First Claim
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.

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.

12. 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, at least two of the plurality of lumens being in fluid communication with an opening at the distal end of the tubular assembly for fluid communication with the patient'"'"'s esophagus and at least one of the plurality of lumens defining a laryngeal lumen having an opening configured for fluid communication with the patient'"'"'s larynx with the distal end extending into the patient'"'"'s esophagus. - View Dependent Claims (13, 14)

15. A method of providing breathing assistance to a patient comprising:
-
providing a tubular assembly comprising a plurality of lumens and a transition portion near a 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 sized to prevent its insertion into the esophagus of a patient;
inserting the distal end of the tubular assembly into the mouth and throat of a patient; and
abutting aryepiglottic folds of a patient with the relatively radially large proximal end to arrest insertion of the tubular assembly into a patient with the relatively radially small distal end of the transition portion extending a select distance into the patient'"'"'s esophagus. - View Dependent Claims (16, 17, 18, 19)
