Endotracheal tube with visualization capabilities and a laryngeal mask

1. A method for intubation of a patient comprising:

positioning a laryngeal mask airway (LMA) in the patient, the LMA comprising a tube connected at a distal end thereof to a mask portion;

positioning an endotracheal tube in the LMA, the endotracheal tube sized and configured to pass through the tube of the LMA and comprising a visualization device at a distal end of the endotracheal tube, the visualization device structured to provide visual images of a distal space distal of the visualization device;

guiding the endotracheal tube through the LMA while visualizing the distal space;

prior to said guiding of said endotracheal tube through said LMA, connecting said visualization device to a display device; and

positioning the distal end of the endotracheal tube in the trachea of the patient; and

removing said LMA from the patient following said positioning while leaving said endotracheal tube positioned in the trachea.

2. The method of claim 1 , wherein said endotracheal tube comprises a single ventilation lumen, a fluid injection channel formed in a wall of the endotracheal tube and extending longitudinally adjacent the single ventilation lumen, and a nozzle fluidly coupled to the fluid injection channel, and wherein said visualization device comprises a lens at a distal end thereof, wherein said endotracheal tube further comprises an injection connector in fluid communication with said nozzle, the method further comprising:

injecting a fluid through the injection connector to discharge the fluid through the nozzle to clean said lens.

3. The method of claim 1 , further comprising:

connecting said LMA to a ventilator following said positioning of said LMA in the patient;

disconnecting said LMA from said ventilator prior to said guiding of said endotracheal tube through said LMA; and

connecting said endotracheal tube to said ventilator following said positioning in the trachea of the patient.

4. The method of claim 3 , further comprising disconnecting said ventilator and said visualization device from said endotracheal tube prior to said removing of said LMA.

5. The method of claim 4 , wherein said mask portion comprises an LMA cuff, further comprising:

inflating said LMA cuff following said positioning of said LMA in the patient; and

deflating said LMA cuff prior to said removing of said LMA.

6. The method of claim 5 , wherein said endotracheal tube comprises a tracheal cuff, the method further comprising:

inflating said tracheal cuff following said positioning in the trachea of the patient.

7. The method of claim 6 , wherein said endotracheal tube comprises a light source, a single ventilation lumen, and a visualization channel formed in a wall of the endotracheal tube and extending longitudinally adjacent the single ventilation lumen, and wherein said visualization device and said light source are positioned in the visualization channel.

8. The method of claim 6 , wherein said endotracheal tube comprises a single ventilation lumen, a fluid injection channel formed in a wall of the endotracheal tube and extending longitudinally adjacent the single ventilation lumen, and a nozzle fluidly coupled to the fluid injection channel, wherein said visualization device comprises a lens at a distal end thereof, wherein said endotracheal tube further comprises an injection connector in fluid communication with said nozzle, the method further comprising:

injecting a fluid through the injection connector to discharge the fluid through the nozzle to clean said lens.
