1. A method of treating a human patient diagnosed with hypertension, the method comprising:

  • advancing a catheter through a radial artery of the patient and into a renal artery of the patient, the catheter having an elongated shaft extending along an axis and comprising a distal portion including a controlled flexure zone and a single distal electrode adjacent to and extending distally beyond the controlled flexure zone;

    establishing contact between the electrode and an interior wall of the renal artery, wherein the controlled flexure zone is configured for controlled flexure about the axis to position the electrode in contact with the interior wall;

    delivering a thermal fluid infusate through the electrode and into the renal artery; and

    delivering energy via the electrode to ablate target tissue along the renal artery.
