Abstract
An annuloplasty ring comprising an elongate tube of suturable material formed into a ring. A stiffener configured to prevent axial compression and radial deformation of the ring is received in the tube in a first circumferential segment of the ring. An axial support configured to prevent axial compression of the ring and to permit radial deformation of the ring is received in the tube in a second circumferential segment of the ring. The first circumferential segment of the ring may correspond to a posterior portion of a mitral valve annulus with the first circumferential portion configured to extend between the right and the left fibrous trigones of the mitral valve annulus upon installation. The second circumferential segment of the ring may correspond to an anterior portion of a mitral valve annulus and the second circumferential segment is configured to extend between the right and left fibrous trigones of the mitral valve annulus upon installation.
