Abstract

Tracheal tube systems may include first and second tubes and an inflatable balloon. The first tube may be flexible and hollow and have first and second open ends. The inflatable balloon may be affixed to and circumferentially surround a portion of the first tube. The inflatable balloon may include an indentation sized and positioned to accommodate a portion of a second tube positioned therein, when the inflatable balloon is inflated. The second tube may be hollow and have a multiplicity of holes along a sidewall not in contact with the balloon. The second tube may be configured to be coupled to a suction device that creates a negative pressure in the second tube. When the tracheal tube system is inserted in a patient'"'"'s trachea, the negative pressure in the second tube may act to remove, or suction out, fluids and other matter from the trachea.

Claims

1. A tracheal tube system comprising:

a first tube that is flexible and hollow and having a first open end and a second open end;

an inflatable balloon affixed to, and circumferentially surrounding an exterior portion of the first tube, the inflatable balloon being positioned between the first open end and the second open end of the first tube; and

a second tube, the second tube being hollow and having a multiplicity of holes along a sidewall of the second tube, the second tube being positioned above the inflatable balloon and surrounding a portion of the first tube, wherein the second tube is configured to be coupled to a suction device that creates a negative pressure in the second tube.

2. The tracheal tube system of claim 1, wherein the second tube is curved.

3. The tracheal tube system of claim 1, wherein the second tube fully encircles a circumference of the first tube.

4. The tracheal tube system of claim 1, wherein the first open end of the first tube is configured to be coupled to an artificial ventilation device.

5. The tracheal tube system of claim 1, wherein the second tube is positioned coincident with a junction between the inflatable balloon and the first tube, the junction being positioned between the first open end of the first tube and the inflatable balloon.

6. The tracheal tube system of claim 1, wherein, when the tracheal tube system is placed in a trachea, the negative pressure created by the suction device acts to suck fluid from the trachea through the multiplicity of holes in the second tube, thereby evacuating the fluid from the trachea.

7. The tracheal tube system of claim 1, wherein the second tube is positioned such that when the tracheal tube system is inserted into a trachea, the inflatable balloon is inflated, and negative pressure is applied to the second tube by the suction device, the second tube is positioned against a portion of a tracheal wall.

8. The tracheal tube system of claim 1, wherein the second tube is positioned such that when the tracheal tube system is inserted into a trachea of a patient and negative pressure is applied to the second tube by the suction device, the second tube is positioned against a posterior portion of a tracheal wall.

9. The tracheal tube system of claim 1, wherein the second tube is affixed to the first tube via at least one of a bond, a sleeve, a clip, a strap, and a clamp.

10. The tracheal tube system of claim 1, wherein the first tube has a lumen coupled to the suction device and negative pressure in the lumen causes negative pressure in the second tube.

11. The tracheal tube system of claim 1, wherein the second tube is flexible.

12. A tracheal tube system comprising:

a first tube that is flexible and hollow and having a first open end and a second open end;

an inflatable balloon affixed to and encircling an exterior portion of the first tube, the inflatable balloon being positioned between the first open end and the second open end of the first tube; and

a second tube positioned on an exterior surface of the first tube so that a portion of the second tube extends partially around a circumference of the inflatable balloon and is substantially perpendicular to the first tube, the second tube being hollow and having a multiplicity of holes along a sidewall.

13. The tracheal tube system of claim 12, wherein the second tube is curved.

14. The tracheal tube system of claim 12, wherein the second tube extends fully around a circumference of the first tube.

15. The tracheal tube system of claim 12, wherein the first open end of the first tube is configured to be coupled to an artificial ventilation device.

16. The tracheal tube system of claim 12, wherein the second tube is positioned coincident with a junction between the inflatable balloon and the first tube, the junction being positioned between the first open end of the first tube and the inflatable balloon.

17. The tracheal tube system of claim 12, wherein, when the tracheal tube system is placed in a trachea, a negative pressure created by a suction device acts to suck fluid from the trachea through the multiplicity holes in the second tube, thereby evacuating the fluid from the trachea.

18. The tracheal tube system of claim 12, wherein the second tube is positioned on the inflatable balloon such that when the tracheal tube system is inserted into a trachea, the inflatable balloon is inflated, and a negative pressure is applied to the second tube by the suction device, the second tube is positioned against a portion of a tracheal wall.

19. The tracheal tube system of claim 12, wherein the second tube is positioned such that when the tracheal tube system is inserted into a trachea of a patient and negative pressure is applied to the second tube by the suction device, the second tube is positioned against a posterior portion of a tracheal wall.

20. The tracheal tube system of claim 12, wherein the second tube is affixed to the first tube via at least one of a bond, a sleeve, a clip, a strap, and a clamp.

21. A surgical device comprising:

a surgical tool, the surgical tool including a tip configured for use within a surgical field; and

a suction line, the suction including a hollow tube that has at least one hole, the suction line being affixed to the surgical tool and positioned so that the at least one hole is substantially coincident with the tip of the surgical tool, wherein the suction line is configured to be coupled to a suction device that creates a negative pressure in the suction line.

22. The surgical device of claim 21, wherein the surgical tool at least one of an ablative surgical tool and a cystoscopic surgical tool.

23. The surgical device of claim 21, wherein the surgical tool is at least one of a scalpel, an endoscope, a clamp, and a pair of microscissors.
