Embodiment Construction

[0019] figure 1 A cross-section of the bronchi is shown with various features of the bronchi marked for reference. The open inner passage (having a diameter marked D in the figures) forms a pathway for air to travel from the person's mouth or nose to the lungs. As can be seen, the walls of the bronchi include multiple components such as epithelium, blood vessels, smooth muscle tissue, mucous glands, nerve fibers, stroma, and cartilage. The nerve or nerve component to be treated by the present invention is positioned towards the outer surface of the bronchial wall (eg, away from its open inner passage).

[0020] figure 2 is a drawing of the autonomic nervous system as it controls a person's pulmonary system. Extending from the brain is the vagus nerve that synapses with the parasympathetic ganglion on the bronchial surface. There is a series of parasympathetic components including postganglionic fibers that form parasympathetic ganglia on the bronchial surface.

Abstract

A method and apparatus for treatment of pulmonary conditions, including a device having an end effector sized and shaped to contact a nerve component on the exterior of a bronchial segment and apply energy to that nerve component.

Description

[0001] This application is a divisional application of the PCT application "Thoracoscopic method for the treatment of bronchial diseases" (application number: 201480063347.9, applicant: Yixikang Company) that entered the Chinese national phase on May 19, 2016. technical field [0002] The present invention relates to methods and devices for the treatment of bronchial diseases including asthma or chronic bronchitis. The present invention relates more directly to methods of delivering energy to one or more nerves on or near the bronchi, and more particularly to methods of applying energy to these nerves through thoracoscopic devices. Background technique [0003] Obstructive lung disease affects millions of people in the United States, limits enjoyment of life and costs billions of dollars to treat. One such disease is asthma, a complex inflammatory disease of the airways characterized by airway hyperresponsiveness and variable airflow obstruction. According to recent estimat...
