  • Artificial heart and its drive unit
    Patent number: 10874779
    Abstract: There is described an artificial heart comprising a pump, the pump comprising a housing (10) defining a substantially spherical cavity and comprising four vascular connectors (15in, 15out, 15?in, 15?out), namely two inlet connectors (15in, 15?in) and two outlet connectors (15out, 15?out) to connect the pump to the pulmonary and systemic circulation. A rotatable disc (11) is mounted within the housing (10) and secured to rotate about a fixed axis (12). Two oscillating palettes (16a, 16b) are mounted to rotate about a mobile axis (17) movable within a plane perpendicular to the fixed axis (12), wherein said palettes (16a, 16b) are connected together and are arranged on both sides of the rotatable disc (11), in a diametrically opposed fashion, to create two pumping units comprising each two variable sized chambers (20a, 20b, 20c, 20d) in fluid communication with one corresponding inlet and outlet connector respectively.
