Abstract:
1. A total artificial heart system for a mammalian cardiovascular system, the total artificial heart system comprising: a first manifold comprising a first manifold inlet coupled to a first atrium of the mammalian cardiovascular system and a first manifold outlet, wherein the first manifold is operable to conduct blood flow through the first manifold from the first atrium to the first manifold outlet; a first pump comprising a first pump inlet coupled to the first manifold outlet and a first pump outlet coupled to a first great vessel of the mammalian cardiovascular system, wherein the first pump is operable to auto-regulate blood flow rate through the first pump in response to a pressure differential between the first pump inlet and the first pump outlet; wherein the first manifold is shaped and configured into an unobstructive geometry to receive and direct blood flow such that a first blood flow pressure at the first manifold inlet is substantially the same as a second blood flow pressure at the first pump inlet; a second manifold comprising a second manifold inlet coupled to a second atrium of the mammalian cardiovascular system and a second manifold outlet, wherein the second manifold is operable to conduct blood flow through the second manifold from the second atrium to the second manifold outlet; a second pump comprising a second pump inlet coupled to the second manifold outlet and a second pump outlet coupled to a second great vessel of the mammalian cardiovascular system, wherein the second pump is operable to auto-regulate blood flow rate through the second pump in response to a pressure differential between the second pump inlet and the second pump outlet; wherein the second manifold is shaped and configured into an unobstructive geometry to receive and direct blood flow such that a third blood flow pressure at the second manifold inlet is substantially the same as a fourth blood flow pressure at the second pump inlet; and wherein the first pump and the second pump each comprise an axial continuous flow pump, and each pump is operable to change the blood flow rate through the pump in response to the pressure differential across the pump.
