An annuloplasty system for repairing incompetent heart valves is provided. This system includes a substantially circular valve reinforcing device adapted to be surgically implanted into around a heart valve annulus; anchoring means for attaching the substantially circular valve reinforcing device to the heart valve, wherein attaching the substantially circular valve reinforcing device to the heart valve annulus reduces the circumference of the heart valve annulus by plicating annular tissue underneath the valve reinforcing device; and constricting means for, if necessary, reducing the circumference of the substantially circular valve reinforcing device, wherein reducing the circumference of the substantially circular valve reinforcing device further reduces the circumference of the heart valve annulus. |
