1. A catheter comprising:
a catheter shaft having a proximal end portion and a distal end portion, the catheter shaft defining a lumen, the lumen configured for at least one of fluid delivery and inflation;
a balloon configured to be coupled to the distal end portion of the catheter shaft, wherein the balloon defines a volume in flow communication with the lumen; and
a plurality of energy transfer elements disposed on a flexible circuit along at least a portion of the balloon, wherein the flexible circuit has a preformed radius of curvature that biases the flexible circuit to bend towards or away from the balloon.
