Abstract
An epicardial defibrillation electrode employing an elongated, coil electrode embedded in the surface of a flexible electrode pad. The coil electrode provides increased flexibility and superior electrode flex life. The arrangement of the coil electrode provides uniform current distribution. The electrode takes the form of a space wound coil following a tortuous path over the surface of the electrode pad to provide a large surface area to reduce current density. In some embodiments, an insulative core is located within the lumen of the coil.
