Devices and methods for tracking an energy device
First Claim
1. A method for tracking an energy delivery device, the method comprising:
- generating a virtual map of airways of a lung using a rendering system;
advancing the energy delivery device within the lung airways and applying an energy therapy to a selected treatment location;
generating a virtual position of the energy delivery device on the virtual map with a sensor assembly coupled to a distal portion of the device;
displaying the virtual map on a visual display; and
automatically preventing, with a controller, application of the energy therapy by the energy delivery device when the energy therapy is demanded by an operator when the controller determines that the energy delivery device is located at one or more previous treatment locations.

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.
