Abstract

Apparatus aiding physiologic systolic and diastolic dynamics of heart cavities designed to assist the systolic contraction of the heart ventricles, and to simultaneously or alternatively regulating the diastolic relaxation, provoking an atrial contraction, the ventricular mode comprising a stiff conical wrapping (12) surrounding the ventricles (11, 11a) fastened to a first ring (13) located on the base of the ventricles and with a distal tip (14) close to the cardiac apex, and a second internal concentrical ring (18) attached to the mouth of a conical bag (19) fastened through a distal vertex (19b) to said tip (14), so that the second ring (18) when rotating provoking in a first course a narrowing of the bag (19) squeezing the ventricles, aiding to the ventricular systole, and in a reverse turn allowing the diastolic filling regulating the ventricular diastole, and the atrial mode comprising a cap (20) surrounding the atria (21, 21a) leading them toward the ventricles (11, 11a) by tension members and wheels associated to the wrapping (12) provoking the atrial systole.
