Abstract

A heart support device for pulsatile delivery of blood comprising a first and a second ventricle and a pump. Both ventricles comprises a fluid chamber and a blood-conveying chamber, wherein each fluid chamber can be filled with a fluid or emptied by way of the pump in such a way that an expansion or contraction of the fluid chamber occurs. In an expansion of the fluid chamber of a ventricle, a compression of the blood-conveying chamber of the same ventricle takes place, wherein a rigid pressure plate is disposed between a fluid chamber and the respective blood-conveying chamber, said pressure plate being able to move in the direction of the respective blood-conveying chamber.
