Devices and methods for tracking an energy delivery device
First Claim
1. A method for treating a lung, the method comprising:
- generating a virtual map of airways of a lung using a rendering system;
stimulating smooth muscle adjacent an airway of the lung to contract the smooth muscle;
analyzing the virtual map to determine a degree of contraction of the smooth muscle;
applying an energy therapy to tissue adjacent to the airway based on the determined degree of contraction of the smooth muscle; and
automatically preventing, with a controller, application of a subsequent energy therapy to a given portion of the airway when the subsequent energy therapy is demanded by an operator and when the controller determines the given portion of the airway has already received an energy therapy.

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.
