1. A body implantable lead, comprising:
- an insulated lead body containing an electrically conductive element;
a first electrically conductive elongate element having an oval or egg-shaped configuration and being electrically coupled to the electrically conductive element;
a second electrically conductive elongate element having a linear configuration and being electrically coupled to the electrically conductive element, the second element bisecting the first element along a long axis of the oval or egg-shaped configuration;
a third electrically conductive elongate element positioned adjacent to and within a perimeter defined by a first half of the bisected first element;
a fourth electrically conductive elongate element positioned adjacent to and a within a perimeter defined by a second half of the bisected first element; and
a support backing attached to the first, second, third, and fourth electrically conductive elongate elements.

Abstract
Body-implantable leads with open, unbacked (uninsulated) electrode structures having electrical discharge surfaces formed by conductive elements, such as mesh and braid, and preferably coils. The electrode structures can be classified by pattern: (1) loops, (2) linear arrays and (3) radial arrays. The electrodes are located on or near the epicardial surface of the right and left heart.
