Abstract: Systems and methods for delivering energy to passageways in a patient, such as airways in the lung of a patient for treating asthma. One embodiment of a method for delivering energy to a passageway comprises positioning an access device in a lung airway of a patient and advancing an elongated body of a treatment device along the access device until an energy delivery unit at a distal portion of the elongated body projects from the access device. The method can further include expanding the energy delivery unit such that energy delivery elements contact a sidewall of the airway and activating an energy supply coupled to the treatment device such that energy is delivered to the sidewall of the airway. A single person physically operates both the access device and the treatment device while expanding the energy delivery unit and activating the energy supply.

Abstract: An energy delivery device for treating tissue regions in a body conduit, such as a lung airway, may utilize one or more markers, rings, bands, or other visual indicators along an outer surface of the device body. The one or more visual indicators facilitate guidance of the device to effectively and efficiently treat the tissue according to a predetermined axial treatment as well as measure extension of a distal portion of the device, tissue length, and/or treatment length. The predetermined axial treatment may be contiguous, overlapping, or intermittently spaced apart as determined by the marker spacing distance.
