Abstract
Methods and apparatus for treating heart failure rely on delivering ultrasonic or other vibrational energy to the heart. The energy may be delivered acutely or chronically, in response to detected cardiac events, in response to manual actuation and/or in response to operation of an implantable defibrillator. The vibrational transducer is implanted so that the vibrational energy can be directed toward at least a portion of the heart in order to increase contractility, vasodilation, tissue perfusion, and/or cardiac output.

29. A system for stabilizing cardiac function, said system comprising:
-
a vibrational transducer implantable in a patient; and
control circuitry for detecting an onset of a cardiac event associated with heart failure and activating the vibrational transducer to deliver controlled vibrational energy to the heart under conditions which treat the heart failure. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
