1. A body implantable lead, comprising:
- an insulated lead body containing an electrically conductive element;
a first electrically conductive element and a second electrically conductive element, each element having linear portions, which are collinear and adjacent, and end portions, each of which is arcuate and diverging from a common point relative to each other, wherein the linear portions have a common proximal end electrically connected to the electrically conductive element; and
a third electrically conductive element and a fourth electrically conductive element radially connected to the common proximal end, wherein a distal end of the third element is interposed between the linear portion and the end portion of the first element, and a distal end of the fourth element is interposed between the linear portion and the end portion of the second element.

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.
