1. A method, comprising:
- providing an instrument to a user, the instrument including an energy emitter positioned at a distal section of the instrument; and
providing instructions to the user for use of the instrument in a denervation procedure, the instructions comprising;
moving the energy emitter through skin of a subject;
wrapping the distal section of the instrument around an airway of a bronchial tree of the subject to position the energy emitter with respect to nerve tissue along the airway of the bronchial tree;
energizing the energy emitter to damage the nerve tissue using energy from the energy emitter while the energy emitter is positioned outside of the airway; and
removing the instrument from the subject.

Abstract
A system and method can be used to denervate at least a portion of a bronchial tree. An energy emitter of an instrument is percutaneously delivered to a treatment site and outputs energy to damage nerve tissue of the bronchial tree. The denervation procedure can be performed without damaging non-targeted tissue. Minimally invasive methods can be used to open airways to improve lung function in subjects with COPD, asthma, or the like. Different sections of the bronchial tree can be denervated while leaving airways intact to reduce recovery times.

12. A method, comprising:
-
providing an instrument to a user, the instrument including an energy emitter positioned on a distal section of the instrument; and providing instructions to the user, the instructions comprising; percutaneously delivering the distal section of the instrument through a skin of a subject and placing the distal section of the instrument around an outer wall of an airway of a bronchial tree of the subject such that the energy emitter is positioned to damage nerve tissue of the bronchial tree; and delivering energy to a first portion of the bronchial tree using the energy emitter of the instrument to substantially inhibit nervous system signals from traveling to a second portion of the bronchial tree. - View Dependent Claims (13, 14, 15, 16, 17, 18)
