1. A system for renal neuromodulation, the system comprising:

  • a catheter comprising an elongated shaft having a proximal portion and a distal portion, wherein the distal portion comprises an electrode configured for intravascular placement within a renal artery of a human patient;

    an energy source coupled to the electrode and configured to deliver radio frequency (RF) energy via the electrode to target neural fibers proximate to a wall of the renal artery,wherein the energy source comprises a component configured to—

    increase energy delivery to a predetermined first power level over a first period of time;

    maintain energy delivery at the first power level for a second period of time; and

    increase energy delivery to a second predetermined power level if a temperature value is less than a preset threshold temperature following the second period of time; and

    wherein the energy source further comprises a component configured to—

    obtain a set of treatment data corresponding to a completed treatment performed using the catheter, the energy source, and the electrode;

    evaluate the set of treatment data in view of one or more criteria to determine if a valuation of the completed treatment is within a pre-determined range; and

    provide an indication as to whether the valuation of the completed treatment is within the pre-determined range.
