Electrode markers and methods of use

A method for treating a lung, comprising:

• positioning an energy delivery element at a first location by aligning a first marker with a reference location;
• delivering energy to lung tissue at the first location with the energy delivery element;
• positioning the energy delivery element at a second location by aligning a second marker with the reference location;
• and
• delivering energy to lung tissue at the second location with the energy delivery element.

A method for treating a lung, comprising:

• delivering energy to lung tissue at a first location with an energy delivery element, the energy delivery element being disposed at or adjacent to a distal end of an elongate member, wherein the elongate member includes a plurality of markers spaced apart from one another;
• determining a second location using the plurality of markers;
• and
• delivering energy to lung tissue at the second location with the energy delivery element.

A method for treating a lung, comprising:

• advancing an energy delivery device into the lung, the energy delivery device having an elongate member with a first marker and a second marker distal to the first marker, and an energy delivery element at or adjacent a distal end of the elongate member, wherein the energy delivery device is advanced into the lung until the first marker is aligned with a reference point;
• delivering energy to the lung when the first marker is aligned with the reference point;
• pulling the energy delivery device proximally until the second marker is aligned with the reference point, the first marker and the second marker being spaced apart from one another by a first distance corresponding to an active region of the energy delivery element;
• and
• delivering energy to the lung when the second marker is aligned with the reference point.
