Abstract

There is provided a balloon cuffed tracheostomy tube with a balloon designed so as to enhance the tube'"'"'s anchorability without sealing the tracheal stoma and to allow for an easier insertion into the trachea than a comparable tube with a thicker balloon. The tracheostomy tube device includes a conventional hollow tube having a proximal end portion, a distal end portion, and a bend region intermediate of the end portions. The distal end portion of the tube is arranged for insertion through a patient'"'"'s throat and tracheal stoma and into the tracheal lumen. The device further includes an inflatable balloon enveloping a portion of the tube. More particularly, the balloon is equal to or less than 30 microns in thickness, allowing for a greater ease of insertion and insertion through a smaller stoma opening, than a comparable tube with a balloon having a thickness greater than 30 microns.

Claims

1. A tracheostomy tube device comprising:

a hollow tube having a proximal end portion, a distal end portion, and a bend region intermediate of the end portions, wherein the distal end portion is arranged for insertion through a patient'"'"'s throat and tracheal stoma and into the tracheal lumen such that the distal end portion of the tube extends in a first direction within the tracheal lumen when the proximal end portion extends in a second direction through the tracheal stoma, the proximal end portion defining a proximal plane of the device;

an inflatable balloon enveloping the tube, the balloon having a distal balloon portion substantially centered about and attached to the distal end portion of the tube and a proximal balloon portion attached to the bend region of the tube and positioned substantially off-center about the bend region below the proximal plane of the device, which upon inflation provides for expansion of the balloon around the distal end portion of the tube and the proximal end portion of the tube below the proximal plane of the device to seal the trachea below the tracheal stoma without sealing the tracheal stoma;

said balloon having walls with a thickness of 30 microns or less, thus providing for insertion into the tracheal stoma with greater ease than a comparable balloon having walls with a thickness of greater than 30 microns; and

means for inflating and deflating the balloon.

2. The tracheostomy tube device of claim 1, where in the balloon has walls having a non-uniform thickness.

3. The tracheostomy tube device of claim 2, wherein a first portion of the balloon has walls having a thickness of about 20 to 30 micrometers and a second portion of the balloon has walls having a thickness of about 5 to about 15 micrometers.

4. The tracheostomy tube device of claim 3, wherein the first portion of the balloon is the portion of the balloon contacting the upper portion of a cross-sectional region of the tracheal lumen and the second portion of the balloon is the portion of the balloon contacting the lower portion of the same cross-sectional region of the tracheal lumen.

5. The tracheostomy tube device of claim 1, wherein the means for inflating and deflating the balloon comprises a flexible conduit in communication with the balloon.

6. The tracheostomy tube device of claim 1, further comprising a flexible conduit along both the tube and the balloon connects the posterior, or cranial, aspect of the balloon, within the first direction inside the trachea, to the environment, such that secretions eventually accumulating cranially to the tracheal stoma can be removed.

7. The tracheostomy tube device of claim 1, wherein the balloon comprises thermoplastic polyurethane polymers, thermoplastic polyolefin elastomers, thermoplastic polyolefin block copolymers, SBS di-block elastomers, SEBS tri-block elastomers and blends and mixtures thereof.

8. A tracheostomy device for insertion into a trachea through a tracheal stoma, comprising a tube and balloon, wherein said balloon upon inflation seals the trachea below the tracheal stoma without sealing the tracheal stoma, said balloon is 30 microns or less in thickness and is positioned substantially off-center about a bend region of said tube, and wherein said balloon allows insertion into a smaller stoma than is needed for a comparable device having a balloon thickness of greater than 30 microns.

9. The device of claim 8 wherein the balloon has walls having a non-uniform thickness.

11. The device of claim 8 further comprising a suction lumen along said tube and balloon such that secretions accumulating cranially to the tracheal stoma can be removed.

10. The device of claim 10 wherein a first portion of the balloon has walls having a thickness of about 20 to 30 micrometers and a second portion of the balloon has walls having a thickness of about 5 to about 15 micrometers.

12. A system for reducing the force to insert a balloon cuffed distal end portion of a tracheostomy tube device through a patient'"'"'s tracheal stoma and into the tracheal lumen such that the distal end portion of the tube extends in a first direction within the tracheal lumen when the proximal end portion extends in a second direction through the tracheal stoma, the distal end portion of the tube being enveloped by an inflatable balloon that is adapted to seal the trachea upon inflation of the balloon, the tracheostomy tube device comprising:

a hollow tube having a proximal end portion, a distal end portion, and a bend region intermediate of the end portions, wherein the distal end portion is arranged for insertion through a patient'"'"'s throat and tracheal stoma and into the tracheal lumen such that the distal end portion of the tube extends in a first direction within the tracheal lumen when the proximal end portion extends in a second direction through the tracheal stoma, the proximal end portion defining a proximal plane of the device;

an inflatable balloon enveloping the tube, the balloon having a distal balloon portion substantially centered about and attached to the distal end portion of the tube and a proximal balloon portion attached to the bend region of the tube and positioned substantially off-center about the bend region below the proximal plane of the device, which upon inflation provides for expansion of the balloon around the distal end portion of the tube and the proximal end portion of the tube below the proximal plane of the device to seal the trachea below the tracheal stoma without sealing the tracheal stoma;

the balloon further having walls with a thickness of 30 microns or less, thus providing for insertion into the tracheal stoma with greater ease than a comparable balloon having walls with a thickness of greater than 30 microns; and

means for inflating and deflating the balloon.

13. The tracheostomy tube device of claim 12, where in the balloon has walls having a non-uniform thickness.

14. The tracheostomy tube device of claim 13, wherein a first portion of the balloon has walls having a thickness of about 20 to 30 micrometers and a second portion of the balloon has walls having a thickness of about 5 to about 15 micrometers.

15. The tracheostomy tube device of claim 14, wherein the first portion of the balloon is the portion of the balloon contacting the upper portion of a cross-sectional region of the tracheal lumen and the second portion of the balloon is the portion of the balloon contacting the lower portion of the same cross-sectional region of the tracheal lumen.
