soft compression fingers 3 in case of any breakdown of the heart compression assembly in the preferred embodiment all components are preferably fabricated from bio compatible materials and are all operating below the endurance limit of the materials to make sure no fatigue failure of any component occurs under such oscillatory loading unloading cycles the preferred compression assembly 30 further includes a control structure 12 b and 12 c that are well known in the art for electromagnetically controlling the operation of heart compression assembly as well as to monitor the actual pressure applied to the cardiac muscles 5 as shown in fig2 the soft compression fingers can also have finger bumps 4 b to enhance localized compression of ventricles base support assembly 12 houses a power source for the device such as at least one long lasting battery 12 a which can be transcutaneously recharged from outside the patient 39 s body not shown within the base support assembly 12 is control circuitry 12 b which preferably includes a microprocessor for the robotic actuations of the linear actuator 11 to preferably provide a pulsating current of the order of 50 to 200 pulses per minute to correspond with the natural pulsations of heart 5 the base support assembly 12 can also have the microprocessor trigger the sino atrial sa or atrio ventricular av nodal activity of.
