1. A method of repairing a patient'"'"'s heart function, comprising:
- providing an annuloplasty ring having a first configuration having a first inner area but configured to assume a second configuration having a second inner area when subjected to a dilatational force, wherein in the first configuration the annuloplasty ring has a generally non-circular shape, in the second configuration the annuloplasty ring has a generally circular shape, and the second inner area is greater than the first inner area; and
restoring the functionality of a native heart valve by implanting the annuloplasty ring in a heart valve annulus of the native heart valve, wherein the annuloplasty ring is implanted in the first configuration and the shape of the heart valve annulus is thereby remodeled to provide proper alignment and closure of the native heart valve leaflets;
and deploying an expandable prosthetic heart valve within the annuloplasty ring and heart valve annulus;
wherein deploying the expandable prosthetic heart valve within the annuloplasty ring and heart valve annulus further comprises;
dilating the annuloplasty ring to transform the annuloplasty ring from the first configuration to the second configuration, to dilate the heart valve annulus.

Abstract
The invention is an annuloplasty ring, and associated methods therefore, configured to reshape a native heart valve annulus to correct heart valve function, and also configured to be reshaped into a generally circular form in order to receive and/or support a prosthetic heart valve. The annuloplasty ring may be configured to have a generally D-shaped configuration when initially implanted to correct native valve function, but to assume a generally circular form when subjected to an outward force such as that provided by a dilation balloon.

9. A method for modifying a native heart valve, comprising:
-
providing an annuloplasty ring having a first substantially rigid configuration having a substantially non-circular shape and a second substantially non-rigid configuration having a substantially circular shape; repairing the functionality of the native heart valve by implanting the annuloplasty ring into a valve annulus of the native heart valve with the annuloplasty ring in the first substantially rigid configuration, wherein after implantation the annuloplasty ring is in the first generally rigid configuration and whereby the shape of the heart valve annulus is thereby remodeled to provide proper alignment and closure of the native heart valve leaflets; and after repairing the functionality of the native heart valve, dilating the annuloplasty ring and valve annulus and crushing the native heart valve leaflets against the valve annulus; wherein dilating the annuloplasty ring and valve annulus and crushing the native heart valve leaflets against the valve annulus comprises deploying an expandable prosthetic valve within the valve annulus. - View Dependent Claims (10, 11, 12, 13)

14. A method of repairing a human heart in the body of a patient, comprising:
-
repairing functionality of a native mitral valve by surgically implanting a substantially D-shaped annuloplasty ring within the valve annulus of the native mitral valve to thereby remodel the valve annulus to a desired substantially non-circular configuration to provide proper alignment and closure of the native heart valve leaflets; and after repairing functionality of the native mitral valve by surgically implanting the substantially D-shaped annuloplasty ring, dilating the native mitral valve to permanently permanently transform the annuloplasty ring into a substantially circular shape and substantially non-rigid configuration and to remodel the valve annulus into a substantially circular configuration; and implanting an expandable prosthetic heart valve within the valve annulus. - View Dependent Claims (15, 16, 17, 18)
