  • Patent number: 10987219
    Abstract: An embodiment includes a chordal replacement system comprising: a pledget coupled to a first suture length and at least one of a first needle and a first ferrule; a second suture length coupled to the pledget and at least a second needle; and a third suture length coupled to the pledget and at least a third needle; wherein the second and third suture lengths are not monolithic with each other and do not constitute a single suture. Other embodiments are described herein.

  • Patent number: 10695169
    Abstract: An embodiment of the invention includes a sewing cuff for aortic heart valves that better approximates native anatomy by better mating with the crown-like anatomical annulus. Limiting distortion of the crown-like annulus provides better blood flow and overall valve function and provides a physician greater ease of implantation since native anatomy is not flattened. Thus, the surgeon may attach sutures to the fibrous tissue of the crown-like anatomical annulus without distorting the shape of the native anatomy. An embodiment includes a scalloped sewing cuff assembly (with semilunar arches) that tracks the crown-like annulus. Another embodiment provides a sewing cuff positioned over the majority of the valve's length, thus allowing the surgeon greater flexibility as to where he or she can attach sutures to the surgical annulus. Conventional valves, which are primarily “low-profile” devices, do not offer such ability. Other embodiments are described herein.
