Abstract:
1. A set of mitral annuloplasty rings for correcting a mitral heart valve annulus from which one can be selected for implant, the set of mitral annuloplasty rings comprising: a set of rings, each ring having a ring body able to resist deformation when subjected to a stress imparted thereon by a mitral valve annulus and arranged around a flow axis having an upward direction and a downward direction, the downward direction corresponding to the direction of blood flow through the mitral valve annulus when the annuloplasty ring is implanted, each ring body in plan view defining, as measured to the inner edge of the ring body, a major axis A extending across the widest point on the ring body and a minor axis B extending across from an anterior segment to a posterior segment perpendicular to the major axis A, and each ring having an identified orifice size; and wherein proportional shapes of the ring bodies are different for different identified orifice sizes to comply with predicted shapes of a particular degenerative valvular disease for different annulus orifice sizes, wherein the ring bodies are three-dimensional with opposite sides of each ring body curving upward above a datum plane to a respective height, and wherein the different proportional shapes of the ring bodies comprises differences in the ratio of the heights of the opposite sides, and wherein, each ring further includes a suture-permeable covering over the ring body.
