Abstract:
A circular artificial heart device comprising:a first toroidal chamber having an outer wall and an inner wall, said inner and outer walls defining a first aperture and having a first outflow openings, said first outflow opening extending outward from an exterior surface of said outer wall and communicating with said first aperture, and having a first intake opening, said first intake opening extending outward from said exterior surface of said outer wall and communicating with said first aperture; said first intake opening and said first outflow opening separated along said outer wall by a first separation arc, said first separation arc larger than an arc subscribed by the larger of said first intake opening and said first outflow opening; a second toroidal chamber having an outer wall and an inner wall, said inner and outer walls defining a second aperture and having a second outflow opening, said second outflow opening extending outward from an exterior surface of said outer wall and communicating with said second aperture, and having a second intake opening, said second intake opening extending outward from said exterior surface of said outer wall and communicating with said second aperture; said second intake opening and said second outflow opening separated along said outer wall by a second separation arc, said second separation arc larger than an arc subscribed by the larger of said second intake opening and said second outflow opening; a first set of a plurality of electromagnet assemblies, each said electromagnet assembly comprising three electromagnets of substantially equal strength and located substantially equidistant from each other in a toroidal configuration perpendicularly about said first toroidal chamber; a first piston and a second piston in the shape of a partial toroid and each subscribing an arc of about the same size of said first separation arc, said first and second pistons positioned within said first aperture; a second set of a plurality of electromagnet assemblies, each said electromagnet assembly comprising three electromagnets of substantially equal strength and located substantially equidistant from each other in a toroidal configuration perpendicularly about said second toroidal chamber; and a third piston and a fourth piston in the shape of a partial toroid and each subscribing an arc of about the same size of said second separation arc, said third and fourth pistons positioned within said second aperture.
