Abstract: This relates to treating airways in a lung to decrease asthmatic symptoms. The also includes steps of measuring a parameter of an airway at a plurality of locations in a lung, identifying at least one treatment site from at least one of the plurality of locations based on the parameter, and applying energy to the treatment site to reduce the ability of the site to narrow.

Abstract: Control systems and methods for delivery of energy that may include control algorithms that prevent energy delivery if a fault is detected and may provide energy delivery to produce a substantially constant temperature at a delivery site. In some embodiments, the control systems and methods may be used to control the delivery of energy, such as radiofrequency energy, to body tissue, such as lung tissue.

Abstract: The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to removal of the occluding material from the blood vessels as well as other body lumens. The devices may include a catheter and a cutter assembly, where the cutter assembly has a distal cutter and a proximal cutter. The devices may also include a drive mechanism, a torque shaft, a deflecting mechanism and a torque control mechanism. The torque control mechanism may sweep the cutter assembly when the cutter assembly is deflected.

Abstract: Methods of increasing gas exchange performed by the lung by damaging lung cells, damaging tissue, causing trauma, and/or destroying airway smooth muscle tone with an apparatus inserted into an airway of the lung are disclosed. The damaging of lung cells, damaging tissue, causing trauma, and/or destroying smooth muscle tone with the apparatus may be accomplished via any one of or combinations of the following: heating the airway; cooling the airway; delivering a liquid to the airway; delivering a gas to the airway; puncturing the airway; tearing the airway; cutting the airway; applying ultrasound to the airway; and applying ionizing radiation to the airway.

Abstract: A method for treating the lung during an acute episode of reversible chronic obstructive pulmonary disease such as an asthma attack. The method comprises transferring energy to an airway wall of an airway such that a diameter of the airway is increased. The energy may be transferred to the airway wall prior to, during or after an asthma attack. The energy may be transferred in an amount sufficient to temporarily or permanently increase the diameter of the airway. The method may be performed while the airway is open, closed or partially closed.

Abstract: This relates to methods and devices for achieving contact between the wall of a cavity or passageway and a medical device when used in tortuous anatomy.

Abstract: Treatment and procedures for treating bodily conduits involves deactivating, killing, or otherwise treating smooth muscle tissue of the conduit.

Abstract: The present invention includes a system for delivering energy to an airway wall of a lung comprising an energy delivering apparatus and a PID controller having one or more variable gain factors which are rest after energy deliver has begun. The energy delivering apparatus may include a flexible elongated member and a distal expandable basket having at least one electrode for transferring energy to the airway wall and at least one temperature sensor for measuring temperature. The PID controller determines a new power set point base on an error between a preset temperature and the measured temperature. The algorithm can be Pi+1=Pi+G(?ei+?ei?1+?ei?2) where ?, ? and ? are preset values and ? is from 1 to 2; ? is from ?1 to ?2; and ? is from ?0.5 to 0.5. In another variation, the controller is configured to shut down if various measured parameters are exceeded such as, for example, energy, impedance, temperature, temperature differences, activation time and combinations thereof.

Abstract: 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 airways 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.
