Abstract
Methods and devices for treating nasal airways are provided.

Claims8
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.
