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.
