Patent ID: 7186210

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; (b) allowing the heart to undergo ventricular systole, during which said potential radially outward expansive force or pressure of said at least one component dynamically increases to a pre-determined magnitude; (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; and whereby said device includes at least one elastic component featuring physicochemical property and behavior of elasticity, whereby said at least one elastic component is positioned adjacent to said at least one part of wall region of the left ventricle and potentially exerts an elastic type of said radially outward expansive force or pressure to said wall region of the left ventricle.
