Abstract
Methods and apparatus are disclosed for attaching cardiac devices onto a natural heart by employing arrays of gripping elements, such as hooks or barbs. The gripping elements are designed to penetrate and lodge themselves in the epicardial tissue in order to secure the device to at least a portion of the surface of the heart muscle. The gripping elements, although designed to penetrate the surface of the heart, have limited depth penetration so as to avoid puncture of blood vessels. The attachment mechanisms disclosed herein can also permit both attachment and detachment of device.
