Abstract
A heart can be artificially contracted to pump blood by separate electromagnets (112) to the exterior surface of the heart and implanting another electromagnet (108) inside a heart chamber. Electric currents are selectively applied to the electromagnets thereby producing magnetic fields which attract the electromagnets. That attraction generates forces which contract chambers of the heart and pump blood from those chambers. A technique for generating an electric current from a natural contraction of the heart is also described,
