Abstract

Methods and devices for treating nasal airways are provided. Such devices and methods may improve airflow through an internal and/or external nasal valve, and comprise the use of mechanical re-shaping, energy application and other treatments to modify the shape, structure, and/or air flow characteristics of an internal nasal valve, an external nasal valve or other nasal airways.

Claims

1. A method for dilating a nasal valve in a nostril of a patient without piercing nasal mucosa of the nostril, the method comprising:

advancing a treatment element of a cryotherapy treatment device into a nostril of the patient in an uninflated configuration, wherein the treatment element comprises an inflatable balloon;

inflating the inflatable balloon to contact nasal mucosa at the nasal valve and dilate the nasal valve to a modified shape;

circulating a low-temperature liquid within the inflatable balloon to apply cryotherapy to tissue underlying the nasal mucosa, thus transferring heat out of the tissue and cooling the tissue;

deflating the inflatable balloon; and

removing the treatment element from the nostril, wherein the nasal valve at least partially retains the modified shape after the treatment element is removed.

2. The method of claim 1, further comprising applying an adhesive strip to an external surface of the patient'"'"'s nose after removing the treatment element from the nostril, to facilitate the nasal valve at least partially retaining the modified shape.

3. The method of claim 1, wherein inflating the inflatable balloon and circulating the low-temperature fluid strengthens the tissue underlying the nasal mucosa.

4. The method of claim 1, wherein the cryotherapy is applied uniformly over an entire outer surface of the inflatable balloon, thereby treating the tissue in contact with the treatment element.

5. The method of claim 1, wherein the low-temperature liquid comprises liquid nitrogen.

6. The method of claim 1, wherein activating the treatment element comprises applying the cryotherapy to a selected tissue depth, and wherein the tissue comprises cartilage at the selected tissue depth.

7. The method of claim 1, wherein the tissue to which the cryotherapy is applied comprises cartilage.

8. The method of claim 1, further comprising determining that the patient suffers from rhinitis.
