Abstract:
1. A method for delivering energy in a lung airway, the method comprising: positioning an access device having a visualization element within a lung airway; advancing an energy delivery device within the access device, wherein a plurality of visual indicators disposed on a distal portion of the energy delivery device and proximal an energy delivery element disposed on a distal end of the energy delivery device are positioned outside the access device as verified with the visualization element so as to provide a predetermined axial treatment in the lung airway with the energy delivery element a predetermined distance relative to the access device; delivering energy to the lung airway from the energy delivery element at the predetermined distance relative to the access device; pulling the energy delivery device in a proximal direction relative to the access device until a next visual indicator disposed on the distal portion of the energy delivery device is verified with the visualization element; and repeating the delivering and pulling steps so as to incrementally deliver energy to the lung airway at a plurality of predetermined axial treatment sites relative to the access device.
