Artificial heart

An artificial heart, including a pump comprising:

• a casing internally defining a substantially spherical cavity;
• a rotating shutter, housed within the substantially spherical cavity and secured thereto so as to be rotatable about an own rotation axis;
• an oscillating shutter, also housed within the substantially spherical cavity and secured to the rotating shutter so as to be rotatable relative to the latter about a rotation axis transversal to the rotation axis of the rotating shutter relative to the casing;
• a guide ring, secured to the oscillating shutter so as to allow the latter to rotate relative to the same guide ring, wherein the guide ring is arranged to move within a seat formed in the substantially spherical cavity while lying in a plane substantially slanting relative to the rotation axis of the rotating shutter and making thereby the rotating shutter rotate,
• said artificial heart being arranged to be connected to a driver so that the latter operates either the rotating shutter through the guide ring or the oscillating shutter through the rotating shutter, wherein the driver is configured to include a muscle or muscle fibers.
