Patent ID: 7993258

Claim:
An in-vivo method for improving diastolic function of the left ventricle of the heart, comprising the steps of: (a) operatively connecting a device in a rest condition to the left ventricle of the heart, wherein said device includes at least one component featuring physicochemical property and behavior for potentially exerting a radially outward expansive force or pressure to at least one part of wall region of the left ventricle during ventricular diastole, wherein said at least one component is operatively connected adjacent to a wall region of the left ventricle by means of at least one component or mechanism selected from the group consisting of: biocompatible pins, biocompatible needles, biocompatible spikes, biocompatible screws, biocompatible clamps, and combinations thereof; (b) allowing the heart to undergo ventricular systole, during which energy is taken from the total energy of the systolic movement of the heart such that said potential radially outward expansive force or pressure of said at least one component dynamically increases to a pre-determined magnitude; and (c) allowing the heart to undergo ventricular diastole, during which said pre-determined magnitude of said potential radially outward expansive force or pressure of said at least one component is dynamically converted into a corresponding kinetic radially outward expansive force or pressure applied to said wall region of the left ventricle, for reducing intracardiac hydrostatic pressure during said ventricular diastole, thereby, improving the diastolic function of the left ventricle of the heart, wherein said method comprises transferring energy only from the systolic stage to the diastolic stage of an overall cardiac cycle such that potential energy stored in the device during the systolic movement of the heart is released as kinetic energy during the diastolic movement of the heart.
