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.
Claims10
A device for delivering energy to a nasal airway to treat rhinitis, the device comprising:
- a handle;
- a shaft extending from one end of the handle;
- a treatment element coupled with a distal end of the shaft, sized to be inserted into a nostril, and configured to change from a first configuration to a second configuration to contact nasal mucosa lining the nasal airway;
- multiple pairs of bipolar radiofrequency electrodes disposed on the treatment element;
- multiple radiofrequency output channels connected with the multiple pairs of bipolar radiofrequency electrodes, wherein each pair of the multiple pairs of bipolar radiofrequency electrodes is connected with a respective one of the multiple radiofrequency output channels;
- and
- at least one impedance sensor configured to measure impedance in the multiple pairs of bipolar radiofrequency electrodes.
