1. A method comprising:
intravascularly advancing an elongate shaft of a catheter to renal vasculature of a patient;
locating a distal portion of the elongate shaft of the catheter within a renal vessel of the patient, wherein the distal portion carries at least one neuromodulation element, and wherein each neuromodulation element comprises a corresponding needle port and a corresponding needle;
imaging at least one radiopaque marker associated with the distal portion of the elongate shaft;
orienting the needle port of the at least one neuromodulation element based on the imaging of the at least one radiopaque marker;
after orienting the needle port based on the imaging, extending the corresponding needle of each of the at least one neuromodulation element to penetrate a wall of the renal vessel; and
modulating nerve tissue within an anatomical region extending about the renal vessel via the neuromodulation element.
