A mitral annuloplasty ring (40) that has an outward (50) and an upward (60) 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.
L'invention concerne un anneau annuloplastique mitral (40) qui comprend un voilement postérieur vers l'extérieur (50) et vers le haut (60). L'anneau définit une forme ovale modifiée fermée comprenant un ratio entre la dimension maximale de l'axe et la dimension minimale de l'axe comprise entre environ 3.3:4 et 4:4. L'anneau est constitué d'un matériau qui résiste sensiblement à la distorsion due à une contrainte que l'anneau subit lorsqu'il est implanté dans l'anneau mitral d'un coeur humain fonctionnant. De cette manière, l'anneau annuloplastique corrige des pathologies associées au prolapsus valvulaire mitral ou au syndrome de Barlow, dans lequel les valvules ont tendance à être allongés ou détendues.
