1. A heart treatment system, comprising:
an elongate lead device including a longitudinal axis, a first zone, a positioning element, and sized and shaped to pass through a transverse pericardial sinus of the heart, the first zone having one or more first zone electrodes providing a first electrical energy, and the elongate lead device further including a proximal-most end, a distal end, and first and second longitudinal side edge lengths, wherein the positioning element is provided intermediate the first zone and the distal end, proximate the distal end and closer to the distal end than the first zone such that the elongate lead device is free of any electrodes intermediate the positioning element and the distal end and intermediate the one or more first zone electrodes and the distal end, with the positioning element including winding curvatures contiguous and without a break with the elongate lead device such that the positioning element is free of any electrodes, and the positioning element is a single contiguous structure, from a beginning to an end of the winding curvatures, and the winding curvatures extend out transverse from the longitudinal axis beyond both of the first and second longitudinal side edge lengths of the elongate lead device to interface with and atraumatically abut an outside margin of the transverse pericardial sinus, without active fixation into tissue, to resist displacement of the elongate lead device in a deployed state.
