1. A method of positioning an energy delivery device, comprising:
imaging at least one radiopaque device that comprises a radiopaque marker carried by the energy delivery device, positioned in at least one of a patient's azygos vein or an intercostal vein, relative to a portion of a spine, using a radiographic imaging device, to thereby characterize a position of the patient's azygos vein relative to a midline of the spine;
determining whether the azygos vein is centered, left-biased or right biased with respect to the midline of a vertebra based on one or more images generated by said radiographic imaging device; and
subsequent to determining whether the azygos vein is centered, left-biased or right biased with respect to the midline of the vertebra, in the patient whose azygos vein is determined to be left-biased with respect to the midline of the vertebra and not centered or right biased with respect to the midline of the vertebra, positioning a distal end of the energy delivery device in the intercostal vein and positioning the radiopaque marker at the midline of the vertebra.
