Abstract
A mitral annuloplasty ring that has an outward and an upward posterior bow. The ring defines a closed, modified oval shape with a minor-major axis dimension ratio of between about 3.3:4 to 4:4. The ring is made of a material that will substantially resist distortion when subjected to the stress imparted thereon when the ring is implanted in the mitral valve annulus of an operating human heart. As a result, the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, or Barlow's syndrome, in which the leaflets tend to be elongated or floppy.
