A heart prosthesis (100) comprises a pulsating mechanism that is surgically placed inside the chest cavity between the sternum (104) and pericardial sac (106). The mechanism's surfaces expand outward and contract inward to knead the heart (108) in step with its natural rhythms. Electromagnetic repulsion and attraction is used to pulse the mechanism surfaces, and a control circuit is connected to drive an electromagnet. |
