1. A method of implanting a prosthetic annuloplasty ring, comprising:

  • providing an annuloplasty ring having a relatively rigid ring core defining a discontinuous periphery around a blood flow orifice with a first free end separated from a second free end across a gap, and a suture-permeable interface surrounding the ring core along its length, wherein the interface includes enlarged floppy regions adjacent both free ends that are larger than any other area of the interface, through which sutures may be passed to secure the annuloplasty ring to a valve annulus, wherein the floppy regions extend radially outward and circumferentially from both free ends toward each other into the gap such that the closest points across the gap are unsupported by the core;

    pre-installing sutures at a valve annulus including passing the sutures entirely through the valve annulus;

    threading the pre-installed sutures through the suture-permeable interface around the annuloplasty ring, including threading at least one suture through each of the enlarged floppy regions;

    parachuting the annuloplasty ring down the pre-installed sutures; and

    securing the annuloplasty ring against the valve annulus using the pre-installed sutures,wherein the interface comprises a molded elastomeric sleeve closely surrounding the ring core and a fabric covering around the sleeve, and the enlarged floppy regions comprise an extension of the fabric covering without the elastomeric sleeve.
