Abstract
An apparatus implantable in a heart ventricle includes a frame configured to engage an inner circumferential periphery of the ventricle and to expand and contract between an expanded state corresponding to a desired end diastolic diameter of the ventricle and a contracted state corresponding to a desired end systolic diameter of the ventricle. A bistable structure is operatively associated with the frame. The bistable structure mechanically assists movement of the ventricle toward both an end systolic diameter during systole and an end diastolic diameter during diastole. The bistable structure may be integrally formed of the frame. A method of implanting the apparatus in a heart ventricle includes surgically accessing a ventricle, inserting the apparatus in the ventricle and attaching the device to a portion of myocardium defining an inner circumferential periphery of the ventricle.
