1. A body implantable lead, comprising:
- an insulated lead body containing an electrically conductive element;
a first electrically conductive element including a first end and a second end coupled to a connection terminal to form a first loop having a first loop apical portion, the first element being electrically connected to the electrically conductive element; and
a second electrically conductive element including a first end and a second end coupled to the connection terminal to form a second loop, wherein the second loop is positioned eccentrically within the first loop and the second element is electrically connected to the electrically conductive 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.
