Patent ID: 8870951

Claim:
A total artificial heart system for a mammalian cardiovascular system comprising a right atrium, left atrium, aorta and pulmonary artery, the total artificial heart system comprising: a first pump comprising a first pump inlet to receive a blood flow and a first pump outlet to pump the blood flow into the pulmonary artery and operable to selectively adjust the blood flow in response to a pressure differential between the first pump inlet and the first pump outlet; a second pump comprising a second pump inlet to receive the blood flow and a second pump outlet to pump the blood flow into the aorta and operable to selectively adjust the blood flow in response to a pressure differential between the second pump inlet and the second pump outlet; a first manifold comprising a first manifold inlet coupled to the right atrium and a first manifold outlet coupled to the first pump, wherein the first manifold transmits the blood flow such that a blood pressure of blood within the right atrium is substantially the same as a blood pressure of blood at the first pump inlet; a second manifold comprising a second manifold inlet coupled to the left atrium and a second manifold outlet coupled to the second pump, wherein the second manifold transmits the blood flow such that a blood pressure of blood within the left atrium is substantially the same as a blood pressure of blood at the second pump inlet; and wherein the first pump and the second pump each comprise a centrifugal pump, and each pump is operable to change the blood flow rate through the pump in response to the pressure differential across the pump.
