1. A method of treating a subject, comprising:
- positioning an ablation assembly with respect to an airway of the subject, wherein the ablation assembly comprises a plurality of energy emitting elements spaced circumferentially about from each other about and axially from each other along a longitudinal axis of the ablation assembly; and
causing energy to be emitted from the ablation assembly to target regions of the airway to create a plurality of axially spaced apart discrete lesions, each lesion extending only partially around a circumference of the airway, wherein an arc length about the circumference of at least one lesion at least partially overlaps with an arc length about the circumference of at least one other lesion of the plurality of lesions.

Abstract
Systems, delivery devices, and methods to treat to ablate, damage, or otherwise affect tissue. The treatment systems are capable of delivering a coolable ablation assembly that ablates targeted tissue without damaging non-targeted tissue. The coolable ablation assembly damages nerve tissue to temporarily or permanently decrease nervous system input. The system, delivery devices, and methods can damage tissue and manage scarring and stenosis.

4. A method of treating a subject, comprising:
-
moving an energy emitter of a delivery device along an airway of the subject, wherein the energy emitter comprises a plurality of energy emitting electrodes spaced circumferentially and axially from each other along a longitudinal axis of the ablation assembly; positioning at least one electrode of the energy emitter between cartilaginous rings of the airway; and causing energy to be emitted from the at least one electrode to target regions of the airway at axially separated locations along a long axis of the airway to form a plurality of inter-cartilaginous lesions, each lesion extending only partially around a circumference of the airway, and wherein at least some of the lesions overlap circumferentially about a long axis of the airway. - View Dependent Claims (5, 6, 7, 8, 9)

10. A method of treating tissue, comprising:
-
positioning an ablation assembly in a lumen of an airway of a subject, wherein the ablation assembly comprises a plurality of electrodes spaced circumferentially and axially from each other along a longitudinal axis of the ablation assembly; and causing energy to be delivered to tissue of the airway using e the plurality of electrodes of the ablation assembly positioned near an inner surface of the airway, wherein the energy damages target regions axially separated along the airway thereby defining lesions having a maximum cross-sectional width radially spaced from the inner surface of the airway. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for treating a subject, comprising:
-
positioning an ablation assembly within an airway of the subject, wherein the ablation assembly comprises a plurality of energy emitting elements spaced circumferentially and axially from each other along a longitudinal axis of the ablation assembly; and causing energy to be delivered from the ablation assembly to form a plurality of lesions, each lesion being axially offset with respect to one another in a direction of a long axis of the airway, wherein each lesion is at least partially adjacent to or overlaps another lesion in a circumferential direction of the airway. - View Dependent Claims (18, 19, 20, 21)
