Degenerative valvular disease specific annuloplasty rings

A mitral annuloplasty ring selected from a set of mitral annuloplasty rings for correcting a mitral heart valve annulus, the set of mitral annuloplasty rings comprising:

• a set of rings each having a ring body able to resist deformation when subjected to the stress imparted thereon by the 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 a major axis A and a minor axis B extending across from an anterior segment to a posterior segment, and each ring having an identified orifice size;
• and
• wherein the proportional shapes of the ring bodies change to comply with predicted shapes of degenerative valvular disease for different annulus orifice sizes.
