  • Patent number: 7695512
    Abstract: Disclosed are implants and methods for remote remodeling of a mitral valve annulus. The implant comprises a body transformable from a flexible configuration for navigation to a treatment site, to a remodeling configuration for, in one application, applying pressure to the posterior leaflet of the mitral valve. On board electronics allow post deployment adjustment of the implant.

  • Patent number: 6858039
    Abstract: A mitral heart valve annuloplasty ring having a posterior bow that conforms to an abnormal posterior aspect of the mitral annulus. The ring may be generally oval having a major axis and a minor axis, wherein the posterior bow may be centered along the minor axis or offset in a posterior section. The ring may be substantially planar, or may include upward bows on either side of the posterior bow. The ring may include a ring body surrounded by a suture-permeable fabric sheath, and the ring body may be formed of a plurality of concentric ring elements. The ring is semi-rigid and the posterior bow is stiff enough to withstand deformation once implanted and subjected to normal physiologic stresses. The ring elements may be bands of semi-rigid material. A method of repairing an abnormal mitral heart valve annulus having a depressed posterior aspect includes providing a ring with a posterior bow and implanting the ring to support the annulus without unduly stressing the attachment sutures.
