Multi-segmented annuloplasty ring prosthesis

摘要

A ring prosthesis (10) which provides different flexibilities at various points about the circumference of an associated heart valve (30). Specifically, the annuloplasty ring prosthesis (10) of the invention includes a segmented body formed by two or more segments (12, 32). The individual segments (24, 26) form a body which is substantially circular and shaped proportional to fit about the annulus of the associated heart valve (30). The individual segments (24, 26) 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 (12, 32) with respect to each other.
