Apparatus aiding physiologic systolic and diastolic dynamics of cardiac cavities

Apparatus aiding the physiologic systolic and diastolic dynamics of cardiac cavities of a patient, said apparatus comprising:

• a stable wrapping (12), acting as receptacle, having a contour similar to that of the ventricles (11, 11a) which it surrounds, the mouthpiece of which is attached to a first stiff ring (13) and with a distal tip (14) on which an apex (10) of the heart will be arranged, both said first stiff ring (13) and said tip (14) being fixed on the body skeleton of the patient;
• a second stiff ring (18), having a slightly smaller diameter, coupled to said first stiff ring (13) which surrounds it, with possibility to revolvingly slide, supported guided on said first ring (13) and moving concentrically to it;
• a bag (19) of flexible fabric, similar to the ventricle contour connected by its mouthpiece (19) to said second stiff ring (18), and a distal vertex (19b) of which is internally joined to said wrapping tip (14));
• means for applying to said second stiff ring (18), during predetermined periods of time rotations to the right and to the left, having an adjustable amplitude, in synchronism with the ventricles (11, 11a) systolic and diastolic cycles determining a twist of the bag (19) which provokes a squeezing of the ventricles (11, 11a) contained within it, aiding so to the systolic emptying and later on , when rotating the ring (18) in an opposite direction, a relaxation which allows the diastolic filling;
• and
• control means to remote monitoring the application during the operating periods of time, of said rotations, in synchronism with the physiologic cardiac dynamics.
