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 after implantation in the mitral valve annulus of an operating human heart. The outward and upward posterior bow of the annuloplasty ring corrects for pathologies associated with mitral valve prolapse, as seen with Barlow's syndrome for instance, in which the leaflets tend to be elongated or floppy. Desirably, the outward bow includes a more pronounced outward bulge having an angular extent that approximately equals the angular extent of the upward bow. Sections adjacent the outward bulge may be relatively straight.
