  • Patent number: 11540918
    Abstract: Prosthetic heart valves and methods of implantation thereof are disclosed herein. In embodiments, a prosthetic heart valve includes a self-expandable frame configured to support of valve member and comprising a plurality of interconnected strut members forming a mesh structure. An inflow end and outflow end portions of the mesh structure respectively define an inflow terminal end and an outflow terminal end of the frame. A portion of the frame tapers inwardly from the inflow terminal end to form a reduced diameter section. In implementations, the frame increases in diameter from the reduced diameter section to an intermediate section. In implementations, the valve member is secured to the frame at the inflow end portion. In implementations, the frame further comprises a plurality of retaining arms that extend from the outflow terminal end and are configured to engage with a valve retaining mechanism of a delivery apparatus.

  • Publication number: 20220338979
    Abstract: Apparatus and methods are described including a docking element (20) configured to be implanted within a subject's left atrium such that no portion of the docking element (20) extends through the subject's mitral valve. The docking element (20) includes a ring (40), a frame (24) extending upwardly from the ring (40), and a radial protrusion (50) configured to extend radially outwardly from the frame, to be disposed in a vicinity of the subject's native mitral annulus, and to generate tissue ingrowth to the radial protrusion from walls of the left atrium at least in the vicinity of the subject's native mitral annulus. A bridging material (56), which is disposed between radial protrusion (50) and the ring (40), forms a seal between the radial protrusion (50) and the ring (40). Other applications are also described.

  • Publication number: 20220331107
    Abstract: Apparatus and methods are described for treating a subject with a diseased mitral valve. A mitral annulus repair device is implanted within the subject's left atrium. The device includes a ring configured to be implanted within 15 mm of a native mitral annulus of the subject, and a frame extending upwardly from the ring, the frame being configured to anchor the mitral annulus repair device within the left atrium, prior to the tissue ingrowth to the mitral annulus repair device occurring, by the frame expanding against inner walls and a roof of the left atrium. The ring is adjustable in size and is configured to reduce a diameter of the subject's native mitral annulus by a diameter of the ring being reduced, subsequent to tissue ingrowth to the mitral annulus repair device having occurred. Other applications are also described.

  • Publication number: 20220226111
    Abstract: Embodiments of a radially collapsible and expandable prosthetic heart valve are disclosed. A valve frame can have a tapered profile when mounted on a delivery shaft, with an inflow end portion having a smaller diameter than an outflow end portion. The valve can comprise generally V-shaped leaflets, reducing material within the inflow end of the frame. An outer skirt can be secured to the outside of the inflow end portion of the frame, the outer skirt having longitudinal slack when the valve is expanded and lying flat against the frame when the valve is collapsed. A diagonally woven inner skirt can elongate axially with the frame. Side tabs of adjacent leaflets can extend through and be secured to window frame portions of the frame to form commissures. The window frame portions can be depressed radially inward relative to surrounding frame portions when the valve is crimped onto a delivery shaft.

  • Publication number: 20220211497
    Abstract: A two-stage or component-based valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The prosthetic valve comprises a support structure that is deployed at a treatment site. The prosthetic valve further comprises a valve member configured to be quickly connected to the support structure. The support structure may take the form of a stent that is expanded at the site of a native valve. If desired, the native leaflets may remain and the stent may be used to hold the native valve open. In this case, the stent may be balloon expandable and configured to resist the powerful recoil force of the native leaflets. The support structure is provided with a coupling means for attachment to the valve member, thereby fixing the position of the valve member in the body. The valve member may be a non-expandable type, or may be expandable from a compressed state to an expanded state.

  • Publication number: 20220008195
    Abstract: Apparatus and methods are described for treating a subject with a diseased atrioventricular valve. A docking element is implanted within the subject's atrium such that no portion of the docking element extends through the subject's atrioventricular valve. The docking becomes anchored to tissue of the atrium at least partially via ingrowth of the tissue of the atrium. The docking element includes a ring, which is implanted at the annulus of the atrioventricular valve, and a frame having a height of at least 15 mm, which extends upwardly from the ring. A prosthetic atrioventricular valve apparatus is placed at least partially inside the docking element subsequent to the ingrowth of the tissue of the atrium having occurred, and becomes anchored to the docking element, at least partially by radially expanding against the ring. Other applications are also described.
