Abstract
Disclosed are various configurations of electrodes with accompanying extensions and wires configured to be attached at or near the left atrium of a heart to allow the device to be held snug against the endocardium and out of the blood flow for low energy defibrillation of the atria in response to atrial fibrillation or other atrial arrhythmias. The portion of the lead internal to the atrium (e.g., the left atrium) is restrained against the endocardium of the left atrium by way of a restraint mechanism. In one example, the electrode is configured to attach to the atrial septum, with wires containing memory-shaped metal to keep the wires against the heart wall. In yet another example, the electrode is configured to be part of a mitral valve device.
