Abstract:
1. A method for assisting the heart in pumping blood, comprising the steps of: providing a device for assisting the heart in pumping blood, the device having an energy absorbing element, an energy delivery element and a flow reversing element, the flow reversing element being coupled to the energy absorbing element to move a first fluid therebetween, the flow reversing element being coupled to the energy delivery element to move a second fluid therebetween; positioning the energy absorbing element to absorb pumping energy of the right ventricle, the absorbing element drawing the first fluid from the flow reversing element when absorbing pumping energy of the right ventricle, the energy absorbing element being positioned against an exterior surface of the right ventricle and being attached to the exterior surface of the right ventricle; forcing the second fluid from the flow reversing element, the flow reversing element using energy absorbed from the right ventricle to force the second fluid out of the flow reversing element; and delivering the second fluid to the energy delivery element which has been forced out of the flow reversing element during the forcing step to provide pumping assistance to the left ventricle, the energy delivery element applying pressure to an exterior surface of the left ventricle.
