Abstract
A ring prosthesis which provides different flexibilities at various points about the circumference of an associated heart valve. Specifically, the annuloplasty ring prosthesis of the invention includes a segmented body formed by two or more segments. The individual segments form a body which is substantially circular and shaped proportional to fit about the annulus of the associated heart valve. The individual segments are held in position with respect to each by a flexible joint. This flexible joint is formed by covering the segments with a flexible material which fits snugly about the segments. The cover is tied off between the adjacent segments to further restrain movement of the segments with respect to each other.
