1. A neuromodulation catheter assembly, comprising:

  • a shaft having a proximal portion and a bifurcated distal portion, wherein the shaft is configured to deliver the distal portion proximate a branch point in a renal blood vessel;

    a first therapeutic arm joined to and extending from the distal portion of the shaft and configured to be delivered into a first branch vessel extending distally from the branch point, the first therapeutic arm having a first energy delivery element;

    a second therapeutic arm joined to and extending from the distal portion of the shaft and configured to be delivered into a second branch vessel extending distally from the branch point, the second therapeutic arm having a second energy delivery element; and

    means for drawing the first and second energy delivery elements towards each other,wherein an angle formed between the first and second therapeutic arms at the bifurcated distal portion is less than a takeoff angle of the branch point.
