An artificial heart, including a pump comprising:
- a casing internally defining a substantially spherical cavity (10) ;
- a rotating shutter (12), housed within the substantially spherical cavity (10) and secured thereto so as to be rotatable about an own rotation axis;
- an oscillating shutter (14), also housed within the substantially spherical cavity (10) and secured to the rotating shutter (12) 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 (18, 18'), secured to the oscillating shutter (14) so as to allow the latter to rotate relative to the same guide ring (18), wherein the guide ring is arranged to move within a seat formed in the substantially spherical cavity (10) while lying in a plane substantially slanting relative to the rotation axis of the rotating shutter (12) and making thereby the rotating shutter (12) rotate,
said artificial heart being characterized in that it is arranged to be connected to a driver so that the latter operates either the rotating shutter (12) through the guide ring (18) or the oscillating shutter (14) through the rotating shutter (12), wherein the driver includes a muscle or muscle fibres. |
