1. An elongated annuloplasty ring, comprising:

  • an elongated ring body comprising an inner single piece metallic structural support surrounded by a suture permeable interface, the ring body surrounding a central open area through which passes a flow axis and being discontinuous so as to define two free ends at a break in continuity around a periphery of the ring body, wherein the ring body has a relaxed configuration shaped to mimic a three-dimensional path along a non-planar native valve annulus,wherein the structural support has a radial cross-section that gradually changes around a length of the structural support and has a C-shaped part in a mid-portion, and wherein the two free ends of the structural support are rectangular in radial cross-section and are more flexible in bending about the flow axis than the C-shaped part of the cross-section, andwherein the suture permeable interface includes a tubular inner portion that surrounds the structural support and an outer flange through which implantation sutures can pass, the outer flange is curved so as to be convex on its outer surface, and the outer flange is connected to the inner tubular portion with a plurality of circumferentially spaced apart radial walls so as to create a celled structure.
