Abstract

Devices and methods are descnbed herein which are directed to the treatment of a patient's heart having, or one which is susceptible to heart failure, to improve diastolic function, by implanting a multiply-πbbed diastolic recoil device, which may or may not additionally compnse a membrane, within a ventπcle of the heart The device may be anchored to said wall by means of said πbs, and may further comprise an atraumatic central hub, spacing said πbs from the bottom of said ventπcle The device may provide an elastic recoil force to said walls of said ventπcle duπng diastole in order to improve ejection fraction, augment movement of said walls, decrease stress in said walls, reduce diastolic pressure of said ventπcle, assist in expansion of said ventπcle, or support a weakened cardiac wall Said membrane may seal against said walls, thereby decreasing ventricular volume and pressure
