Abstract
An annuloplasty prosthesis ring for implantation proximate a heart valve orifice includes a core having a size and shape to generally conform to the heart valve orifice. A sheath formed about the core is adapted for receiving a suture therethrough to attach the annuloplasty ring to the heart valve orifice. The suture is knotted on a knot surface of the sheath to form a suture knot thereon. A moveable suture guard is provided which is moveable between an open position in which the knot surface and suture knot are exposed and a closed position in which the knot surface and the suture knot carried on the knot surface are covered.
