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.

Claims

1. A device for treating a patient'"'"'s nasal airway, the device comprising:

a first handle that bifurcates to form a first shaft and a second shaft;

a first energy-based treatment element located at a distal end of the first shaft, the first energy-based treatment element configured to be inserted into a first nostril of the patient'"'"'s nasal airway and apply energy to or remove energy from tissue of the patient'"'"'s nasal airway;

a second treatment element located at a distal end of the second shaft, the second energy-based treatment element configured to be inserted into a second nostril of the patient'"'"'s nasal airway and apply energy to or remove energy from tissue of the patient'"'"'s nasal airway; and

a second handle connected to the first handle and extending distally to a mold, wherein the first handle and the second handle are connected so that squeezing the two handles causes the first energy-based treatment element and the second energy-based treatment element to be compressed toward the mold.

2. The device of claim 1, wherein the first and second energy-based treatment elements are configured to apply energy selected from a group consisting of radiofrequency, heat, electrical, ultrasound, microwave, and cryogenic energy.

3. The device of claim 1, wherein the mold is configured to be placed on a bridge of the patient'"'"'s nose and provide at least one of counter-traction, compression of tissue, positioning, or external tissue deformation.

4. A method for treating a patient'"'"'s nasal airway, the method comprising:

positioning a first treatment element within a first nostril of the patient'"'"'s nasal airway adjacent to a nasal tissue to be treated, wherein the first treatment element is disposed at a distal end of a first elongate shaft extending from a bifurcated first handle;

positioning a second treatment element within a second nostril of the patient'"'"'s nasal airway, wherein the second treatment element is disposed at a distal end of a second elongate shaft extending from the bifurcated first handle;

positioning a mold on a bridge of the patient'"'"'s nose, wherein the mold extends proximally to a second handle connected to the first handle;

squeezing first and second handles to cause the first and second treatment elements to be compressed toward the mold; and

applying energy to or removing energy from the nasal tissue with the first and second treatment elements.

5. The method of claim 4, wherein squeezing the first and second handles alters a shape of the nasal tissue, and wherein the nasal tissue at least partially maintains the altered shape after the first and second treatment elements are removed and the nasal tissue heals.

6. The method of claim 4, wherein positioning the first treatment element and positioning the second treatment element occur simultaneously, and wherein applying energy to or removing energy from the nasal comprises simultaneously delivering energy from the first and second treatment elements.
