Abstract
Two redundant hearts are operated simultaneously for normal patient activity, one of said hearts having sufficient capacity to maintain life at a reduced activity in the event of failure of the other. A single housing contains two brushless DC motors that pump hydraulic fluid to diaphragms which are part of the two respective hearts. The diaphragms operate, on the blood side, to pump blood in a single blood system connected respectively to the aorta, left atrium, right atrium and pulmonary artery. If one motor fails, the remaining motor will pump sufficient blood to keep the patient alive until the heart can be replaced.
