Method and apparatus for ventilation / oxygenation during guided insertion of an endotracheal tube
First Claim
1. An apparatus for guiding insertion of an endotracheal tube into the trachea of the patient while ventilating the patient, said apparatus comprising:
- a tubular guide to direct insertion of an endotracheal tube through the guide into a patient'"'"'s trachea;
said guide having a curved distal portion for insertion into a patient'"'"'s mouth and hypopharynx to a position above the patient'"'"'s larynx, and a proximal end extending out of the patient'"'"'s mouth; and
a second lumen extending along the guide to supply air/oxygen into the patient'"'"'s lungs through the larynx.

Abstract
A method and apparatus for guiding insertion of an endotracheal tube into a patient'"'"'s trachea simultaneously allows a continued supply of air/oxygen to be delivered into the patient'"'"'s airway and lungs. A guide having a curved distal portion is inserted into the patient'"'"'s mouth and hypopharynx. A second lumen extending along the guide is used to supply air/oxygen into the patient'"'"'s airway and to flush carbon dioxide from the lungs. A fiber optic probe is inserted through an endotracheal tube and this assembly is advanced along the guide into the patient'"'"'s airway, while ventilation continues without interruption through the second lumen. The direction of the distal tip of the fiber optic probe can be controlled by the physician. This allows the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while ventilation continues. After the distal end of the fiber optic probe has guided the endotracheal tube past the larynx and into the trachea, the guide and mask are withdrawn over the fiber optic probe. The fiber optic probe can used to monitor the position of the distal end of the endotracheal tube during this step to ensure that it remains in position. The fiber optic probe is then removed from within the endotracheal tube. The cuff on the endotracheal tube is inflated and a ventilator is connected to the proximal end of the endotracheal tube to ventilate the patient.

13. An apparatus for guiding insertion of an endotracheal tube into the patient'"'"'s trachea while ventilating the patient, said apparatus comprising:
-
a tubular guide having a curved distal portion for insertion into a patient'"'"'s mouth and hypopharynx to direct insertion of an endotracheal tube into the patient'"'"'s trachea;
a fiber optic probe insertable through an endotracheal tube;
a stabilizer removably attachable to the fiber optic probe, said stabilizer having dimensions sufficiently large to push the endotracheal tube forward as the fiber optic probe is advanced along the guide and into the patient'"'"'s trachea; and
a second lumen extending along the guide to supply air/oxygen into the patient'"'"'s lungs through the larynx. - View Dependent Claims (14, 15, 16, 17)

18. A method for resuscitating a patient and guiding insertion of an endotracheal tube into the patient'"'"'s trachea comprising:
-
inserting a tubular guide into a patient'"'"'s mouth and hypopharynx, said guide having a curved distal portion shaped to allow insertion of an endotracheal tube through the guide into a patient'"'"'s trachea, said guide further having a second lumen extending along the guide;
inserting the fiber optic probe into an endotracheal tube;
advancing the fiber optic probe and endotracheal tube so that the endotracheal tube advances along the guide and into the patient'"'"'s trachea;
supplying air/oxygen via the second lumen into the patient'"'"'s lungs while advancing the endotracheal tube and fiber optic probe;
removing the guide from the endotracheal tube;
removing the fiber optic probe from the endotracheal tube; and
ventilating the patient through the endotracheal tube. - View Dependent Claims (19, 20, 21, 22)
