Devices to treat nasal airways

A device for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway, the device comprising:

• a handle;
• only one elongate shaft extending from one end of the handle;
• and
• only one treatment element extending from an end of the elongate shaft that is opposite the handle, wherein the treatment element is sized to be inserted into a nostril and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy to modify the property of the nasal tissue, and wherein the treatment element comprises:
• a front, tissue contact surface having a convex shape configured to at least temporarily deform the nasal tissue into a concave shape;
• a back surface;
• two rows of protruding, bipolar, radiofrequency electrodes disposed along a length of the tissue contact surface, wherein the device is configured to deliver radiofrequency energy from one of the two rows of electrodes to the other of the two rows of electrodes;
• and
• a heat sensor disposed on the tissue contact surface of the treatment element, between the two rows of electrodes.
