Abstract
An implantable epicardial lead (13) is provided which is comprised of two spherical ICs (25) and (26) disposed at opposite ends of a supporting structure and separated by a predetermined distance. These spherical ICs comprise an anode and a cathode, each having connections thereto. The epicardial lead (13) includes circuitry for allowing inductive coupling of power into the epicardial lead (13) for storage in a capacitor (926). A switch (928) allows for selective discharge of the capacitor (926) to the surrounding myocardium into which it is implanted. The epicardial lead (13) also includes a receive/transmit device (942) for receiving command information for storage in a memory (939) to provide operation information therefor and also for receiving sensed information therefrom. The sensed information is sent via a switch (930).
