Abstract:
1. A ventricular function assisting apparatus comprising anchoring means capable of being attached to the wall of the heart, elastic elements capable of being attached to said anchoring means, at least two restrictive elements adapted to encircle a perimeter of the heart, said restrictive elements are capable of being changed between an engaging state and a non-engaging state over the heart, and elongated flexible elements capable of being attached between said restrictive elements via their extremities while being movably engaged in said anchoring means along portions of their lengths, wherein said elastic elements are capable of being elastically deformed and store potential energy in them during the systolic phase and release said stored energy during the diastolic phase and thereby apply radially outward and tangentially directed forces over the wall of the heart, wherein said ventricular function assisting device is capable of being selectively changed between two modes of operation by changing the state of said restrictive means between their non-engaging and engaging states over the heart, and wherein the elastic elements are made in a “V”-like shape having torsion loop(s) at their apexes and two side arms attached at one end to said torsion loop(s), and wherein each of said side arms comprises attachment components at their free ends capable of being received and held in the anchoring means.
