摘要： An apparatus and method are provided for treating collapsed bronchial tubes found in patients with chronic obstructive pulmonary diseases, such as asthma. The apparatus delivers energy to inductively heat the tissue of the bronchial tube by directing electromagnetic energy into the tissue. The apparatus includes expandable electrodes that come into contact with the walls of the bronchial tubes. The expandable electrodes may be conical-shaped electrodes, loop-shaped electrodes, plate-shaped electrodes, or other shapes. The method includes heating the bronchial tube to cause tissue in the wall of the bronchial tube to undergo a structural transformation effective to render the wall capable of supporting a non-collapsed lumen. The procedure effectively reinforces the structural integrity of the bronchial tube wall and thereby prevents the lumen from collapsing.

摘要： This relates to methods and devices for treating reversible chronic obstructive pulmonary disease, and more particularly, relates to a device for exchanging energy with airway tissue such as that found in the airway of human lungs. The exchange of energy with this airway tissue in the airways reduces the ability of the air ways to constrict and/or reduces the resistance within the airway to the flow of air through the airway. This also relates to a method for decreasing responsiveness or decreasing resistance to airflow of airways involves the transfer of energy to or from the airway walls to prevent or reduce airway constriction and other symptoms of lung diseases. The treatment reduces the ability of the airway to contract during an acute narrowing of the airways, reduces mucus plugging of the airways, and/or increases the airway diameter. The methods according to the present invention provide a longer duration and/or more effective treatment for lung diseases than currently used drug treatments, and obviate patient compliance issues. This also includes additional steps that reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease and to reduce the resistance to the flow of air through a lung.

摘要： This relates to treating an asthmatic lung and more particularly, relates to advancing a treatment device into the lung and treating the lung with the device. This also includes additional steps of treating the airway wall, applying energy or heat to the airway wall in an asthmatic lung.
