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.
Claims7
A method for deactivating tissue in a nasal airway in a patient, the method comprising:
- inserting a cryotherapy balloon of a nasal airway treatment device through a nostril of the patient in an uninflated configuration;
- inflating the cryotherapy balloon by circulating a liquid into an interior of the cryotherapy balloon to contact the cryotherapy balloon with nasal mucosa lining the nasal airway;
- removing energy from submucosal tissue underlying the nasal mucosa by maintaining the cryotherapy balloon in an inflated configuration and continuing to circulate the liquid through the interior of the cryotherapy balloon to deactivate the submucosal tissue underlying the nasal mucosa;
- removing the liquid from the interior of cryotherapy balloon;
- and
- removing the cryotherapy balloon from the nasal airway.
