1. A catheter apparatus for treatment of a human patient via renal denervation, the catheter apparatus comprising: a therapeutic assembly having a central axis and a distal portion and a proximal portion axially spaced along the central axis, the therapeutic assembly including— a plurality of energy delivery elements including at least a first energy delivery element and a second energy delivery element; and a shapeable region moveable between a delivery state and a deployed state, wherein the plurality of energy delivery elements are carried by the shapeable region; a control member operably coupled to at least a portion of the therapeutic assembly and disposed along the central axis such that the first and the second energy delivery elements are axially and radially spaced from one another about the control member, and wherein— proximal movement of the control member relative to the distal portion of the therapeutic assembly places the therapeutic assembly in the delivery state; and distal movement of the control member relative to the distal portion of the therapeutic assembly places the therapeutic assembly in the deployed state.
