ABSTRACT:
The present invention relates to a heart prosthesis/artificial heart comprising a series of drawing and pressing devices. The prosthesis/artificial heart is to be implanted in a patient to replace the pumping activity of a heart. The heart comprises at least two compartments (5, 6, 12, 13, 25, 26, 27, 28), substantially surrounded by a rigid-wall provided house (2, 3, 31). The house contains a number of drawing and/or pressing devices (10, 48, 50), which are partly fixedly attached to the rigid-wall provided house (2, 3, 31) and are partly fixedly attached to a flexible, elastic wall layer (7, 30) arranged in a respective compartment. The drawing and/or pressing devices (10, 48, 50) are arranged to draw the elastic wall layers (7, 30) towards the rigid-wall provided house (2, 3, 31) for filling the compartments (12, 13, 27, 28).
