DEVICES TO TREAT NASAL AIRWAYS
First Claim
1. 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;
an elongate shaft extending from a first end of the handle; and
a treatment element extending from a second end of the elongate shaft that is opposite the first end, 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; and
a monopolar radiofrequency electrode disposed on the tissue contact surface of the treatment element.

Abstract
A device is described 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. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.
