The device comprises an external bag (1) of synthetic material and shaped like a warhead cap, provided with a rigid shell (2), configured like a hull, and covering the inside of the bag (1) only on a portion of its surface, and supporting two individual ventricles made of synthetic material (3). Each individual ventricle (3) comprises an external rigid envelope (8) which is also shaped like a warhead cap, and carries at its apical extremity an actuator (4) acting on an intermediary synthetic bag (9) having a shape similar to that of the rigid envelope (8) in order to cause the cyclic deformation of a pericardial bag (10) contained in the intermediary bag (9).
