It aids the systolic contraction of the ventricles of the heart, being also capable to regulate the diastolic relaxation, simultaneously or alternatively, to provoke the atria contraction. The ventricular mode comprises a stiff conical wrapping (12) fastened to a first ring (13) located on the bottom of the ventricles (11, 11a) and on a vertex (14) close to the cardiac apex. A second concentrical ring (18) rotatory inside the first, has a conical bag (19) fastened with a vertex fixed to the point (14). The second ring (18) when rotating provokes a narrowing of the bag (19) squeezing the ventricles, aiding to the ventricular systole, regulating its speed, duration and amount. The return of the second ring (18) allows the diastolic filling regulating the ventricular diastole. The atria mode comprises a cap (20) surrounding the atria (21, 21a) lead toward the ventricles (11, 11a) by tension members and wheels associated to the wrapping (12) provoking the atria systole. <IMAGE> |
