CLAIMS

What is claimed is:

1. A device for use with existing endotracheal tubes comprising, a first segment defining a first lumen and comprising a proximal and a distal end, and a second segment defining a second lumen and comprising a proximal and distal end, wherein the first segment is adjacent to, and runs along a parallel axis with, the second segment, and wherein the first segment is sized to accommodate a bronchoscope and the second segment is sized to accommodate an endotracheal tube.

2. The device of claim 1, wherein the first segment and the second segment are defined within a single tubular component.

3. The device of claim 1, wherein the first segment and the second segment are defined by separate tubular components that are joined circumferentially along a common axis.

4. The device of claim 1, wherein the distal ends of the first segment and the second segment attach to an inflatable balloon.

5. The device of claim 4, wherein the balloon is a laryngeal mask airway balloon.

6. The device of claim 1, wherein the first segment, the second segment, or both, further comprise a cap at the proximal end, the cap comprising a slit in a top surface of the cap.

7. The device of claim 6, wherein the cap is made of silicon rubber or poly-vinyl chloride.

8. The device of claim 1, wherein the distal tip of the first segment may be beveled.

9. The device of claim 1, wherein the first segment has a Shore A durometer rating of between approximately 50 and 80, and the second segment has a durometer reading of between approximately 50 and 80.

10. The device of claim 1, wherein the first segment comprises one or more removable or slidable segments to facilitate adjustments to the length of the first segment.

11. The device of claim 1 , wherein the second segment comprises a set of tracks and the first segment comprises a set of corresponding locking mechanisms to facilitate circumferential locking of the first and second segment.

12. The device of claim 1, further comprising a handle, the handle being positioned between the first and second segment and made of a hard plastic or metal material, wherein the hard plastic or metal material is covered with a soft plastic layer.

13. The device of claim 12, wherein the handle comprises a groove or channel that houses a portion of the first segment.

14. The device of claim 12, wherein the handle further comprises bite blocker comprising a cylindrical tube located on the handle so as to be positioned near a subject's teeth after intubation of the device.

15. The device of claim 1, wherein the first segment comprises a handle portion on the distal end, the handle portion having a larger outer diameter and higher durometer rating than the rest of the first segment and a same inner diameter as the rest of the first segment.

16. The device of claim 15, wherein the first segment further comprises an esophageal drainage tube.

17. The device of claim 1, wherein the length of the first segment is between 9 cm and 24 cm, and the second segment has a length of between 4 cm and 8 cm.

18. A method of performing a tracheostomy procedure comprising: inserting the device according to any one of claims 1 to 17 into the oropharynx of a subject with an existing endotracheal tube, wherein the second segment is inserted over the existing endotracheal tube, and the first segment is placed slightly distal to vocal chords of the subject;

inflating the inflatable balloon of the device;

deflating the balloon of the existing endotracheal device;

inserting a bronchoscope into the first segment; and

removing the existing endotracheal device until the distal tip of the existing endotracheal device is just clear of a target incision cite as shown by images captured using the bronchoscope.
