  • Patent number: 10828025
    Abstract: An embodiment includes a system comprising: first and second conduits respectively including first and second barbed rods; first and second shafts; wherein: (a)(i) in a first configuration the first shaft slides distally within the first conduit and couples to a proximal end of the first barbed rod, and (a)(ii) in a second configuration the first shaft slides distally within the first conduit and pushes the first barbed rod out of the first conduit; wherein: (a)(i) in an additional first configuration the second shaft slides distally within the second conduit and couples to a proximal end of the second barbed rod, and (a)(ii) in an additional second configuration the second shaft slides distally within the second conduit and pushes the second barbed rod out of the second conduit. Other embodiments are described.

  • 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.

  • Patent number: 10213303
    Abstract: An embodiment includes an apparatus comprising: a hollow needle with a narrowed inner diameter in a distal third of the needle; and a flexible chord coupled to proximal and distal conduits; wherein the distal conduit is in the needle and distal to the narrowed inner diameter and the proximal conduit is in the needle and proximal to the narrowed inner diameter; wherein: (a)(i) long axes of the proximal and distal conduits are substantially parallel to a long axis of the needle when the proximal and distal conduits are in the needle, and (a)(ii) the proximal and distal conduits are configured to rotate when deployed from the needle such that their long axes are not parallel to a long axis of the chord when the chord is fully extended. Other embodiments are described herein.

  • Patent number: 8303652
    Abstract: A heart valve holder-inserter (21, 121) is designed to facilitate easy implantation of a mechanical heart valve prosthesis (23, 123). This holder-inserter, at its distal end, incorporates a pair of diametrically opposed guide members (47, 49, 81, 147, 149) which extend well beyond the leading edge of the prosthesis and which have exterior surfaces (53, 83, 153) of substantial dimension that are smoothly curved and proportioned so as to slowly spread the tissue annulus in order to facilitate easy entrance thereinto of the leading edge portion of the mechanical valve body.
