Abstract:
Methods for treating a network of organs including generating a map of at least a portion of the network of organs using a rendering system; selecting at least one treatment location within the luminal passageway of the network of organs; and applying an energy therapy to the treatment location to treat the smooth muscle tissue, where the energy therapy applied to the respective treatment location is defined by a plurality of parameters that are associated with a map. Such a system allows for historical or ideal treatment parameters to be identified, visually or otherwise to actual treatment locations. Also, 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.

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:
A method for treating a subject includes positioning an intraluminal device at a treatment location in an airway of the subject, and delivering energy from an electrode of the intraluminal device to nerve tissue extending along the airway so as to permanently damage the nerve tissue while cooling airway tissue disposed radially between the electrode and the nerve tissue.
Abstract:
An energy delivery device may include an elongate member having a proximal portion, a distal portion, and a lumen extending therebetween. The device may include a deployment member extending through the lumen toward a distal tip of the energy delivery device, and an expandable basket having a plurality of curved electrode legs. Each of the curved electrode legs may have a first end coupled to the distal portion of the elongate member and a second end coupled to the deployment member, and each of the plurality of curved electrode legs may have at least one energy insulated region and one energy active region. The device also may include at least one temperature sensing element coupled to said expandable basket.
Abstract:
The present disclosure may include 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. 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.
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:
This relates to treating reversible chronic obstructive pulmonary disease, and more particularly, to exchanging energy with airway tissue such as that found in human lungs. This exchange of energy reduces the ability of the airways to constrict, reduces the resistance within the airway to the flow of air through the airway, reduces mucus plugging of the airways, and/or increases the airway diameter. This energy exchange also may reduce the ability of the lung to produce at least one of the symptoms of reversible obstructive pulmonary disease.
Abstract:
An embodiment of the disclosure includes a method for treating a lung. The method may include inserting a cooling element into an airway of the lung; and damaging tissue disposed radially outward of surface tissue defining the airway via the cooling element
