Abstract

The present invention is a collapsible nasal-oropharyngeal tube and a method of its use. The collapsed tube is inserted via a patient'"'"'s nostril, then expanded when properly located in the upper airway. Collapsing the tube prior to insertion, facilitates insertion, minimizes trauma to the nasal passage, and allows self insertion by the patient. The expanded tube'"'"'s lumen defines an unobstructed airway, and thus maintains upper airway patency. The nasal-oropharyngeal tube can be used as a treatment of nasal-oropharyngeal obstructions, sleep apnea, and other related disorders.

Claims

1. A device comprising:

a collapsible nasal-oropharyngeal tube having a proximate end and a distal end, and having expanded and collapsed states, wherein in the expanded state the distal end of the nasal-oropharyngeal tube is flared, and wherein in the expanded state the lumen of said tube defines an unobstructed airway, and in the collapsed state at least said tube'"'"'s distal end width is reduced; and

a retaining mechanism connected to said tube;

wherein said retaining mechanism is capable of holding said tube in a collapsed state, and wherein said tube, when collapsed, is insertable into a patient'"'"'s nasal-oropharyngeal airway.

2. The device of claim 1, further comprising a retaining mechanism release connected to the retaining mechanism.

3. The device tube of claim 2, wherein the tube is expandable by releasing the retaining mechanism, wherein the lumen of the expanded tube defines an unobstructed airway, and wherein the expanded tube can maintain nasal-oropharyngeal patency.

4. The device of claim 2, wherein the retaining mechanism release is a release fiber connected at its distal end to the retaining mechanism, and capable of breaking the retaining mechanism if pulled.

5. The device of claim 1, wherein the tube can extend from the nostril opening to the oropharynx of a patient.

6. The device of claim 1 wherein the largest diameter of the expanded tube is located near the oropharynx.

7. The device of claim 1 wherein the tube comprises a hypoallergenic material.

8. The device of claim 1 wherein the tube comprises PVC, polyurethane, polyethylene or polypropylene.

9. The device of claim 1, further comprising an anesthetic coating.

10. The device of claim 1, further comprising a lubricant coating.

11. The device of claim 1, further comprising fenestrations in the nasal-oropharyngeal tube.

12. The device of claim 1, further comprising a continuous positive airway pressure compressor connected via a regulating valve to the proximate end of the nasal-oropharyngeal tube.

13. The device of claim 1, further comprising an implanting device, the implanting device comprising a mandrel wherein at least a portion of the length of the mandrel is expandable and collapsible,

wherein the mandrel is mounted collapsed through the lumen of the nasal-oropharyngeal tube,

wherein the nasal-oropharyngeal tube is collapsed,

wherein the expandable portion of the mandrel is located within the nasal-oropharyngeal tube'"'"'s lumen, and

wherein the mandrel is capable of releasing the retaining mechanism by expanding.

14. A device comprising:

a collapsible nasal-oropharyngeal tube having expanded and collapsed states, wherein in the expanded state the lumen of said tube defines an unobstructed airway, and in the collapsed state at least said tube'"'"'s distal end width is reduced, wherein the nasal-oropharyngeal tube is collapsed;

a mandrel mounted through the lumen of the nasal-oropharyngeal tube; and

a sheath having a lumen, wherein the sheath covers the nasal-oropharyngeal tube and the sheath'"'"'s lumen retains the nasal oropharyngeal tube in a collapsed state;

wherein the device is insertable into a patient'"'"'s nasal-oropharyngeal airway, and wherein the nasal-oropharyngeal tube can be deployed by inserting the device in a patient'"'"'s nose, expanding the nasal-oropharyngeal tube by removing the sheath and uncovering the nasal-oropharyngeal tube, and removing the sheath and the mandrel.

15. A device comprising:

a collapsible nasal-oropharyngeal tube having expanded and collapsed states, wherein in the expanded state the lumen of said tube defines an unobstructed airway, and in the collapsed state at least said tube'"'"'s distal end width is reduced;

a retaining mechanism connected to said tube; and

a retaining mechanism release connected to the retaining mechanism;

wherein said retaining mechanism is capable of holding said tube in a collapsed state, wherein said tube, when collapsed, is insertable into a patient'"'"'s nasal-oropharyngeal airway, wherein the tube is expandable by releasing the retaining mechanism, wherein the lumen of the expanded tube defines an unobstructed airway, and wherein the expanded tube can maintain nasal-oropharyngeal patency.
