1. An intravascular device, comprising:
an elongated catheter body having a proximal end and a distal end;
a plurality of conduits extending within the elongated catheter body, wherein distal ends of the conduits terminate at different axial locations along the distal end of the catheter body;
a controller; and
a linkage coupled between proximal ends of the conduits and the controller, wherein the linkage is configured for, in response to a single energy input applied to the linkage by the controller, simultaneously applying a plurality of energy outputs respectively to the proximal ends of the conduits at a preset control parameter ratio;
wherein the distal end of the elongated catheter body is configured for assuming a compound curve comprising a plurality of bends in response to the application of the plurality of energy outputs by the linkage to the proximal ends of the conduits.
