    摘要: A prosthetic heart valve includes a collapsible and expandable annular frame. The frame includes a plurality of rows of hexagonal cells. Each of the hexagonal cells is defined by six struts, including: two opposing side struts extending parallel to each other, a first pair of angled struts extending from respective first ends of the side struts and converging to intersect with each other, and a second pair of angled struts extending from respective second ends of the side struts and converging to intersect with each other. The prosthetic heart valve can also include a valvular structure with a plurality of leaflets. The prosthetic heart valve can further include a sealing member.

    摘要: A prosthetic heart valve includes a frame, a valve member, and a sealing member. The frame is expandable from a collapsed state to an expanded state. The frame has inflow and outflow ends, a lumen extending between the ends, and a plurality of struts defining a plurality of cells. The valve member is disposed within the lumen of the frame and is movable between open and closed configurations. The sealing member is mounted inside of the frame. When the frame is in the expanded state and the valve member is in the closed configuration, portions of the sealing member can protrude outwardly through the cells of the frame and extend beyond an exterior surface of the struts of the frame.

    摘要: Embodiments of a prosthetic heart valve are disclosed. An implantable prosthetic valve may be radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The prosthetic valve may comprise an annular frame, a leaflet structure positioned within the frame and a plurality of outer skirts positioned around an outer surface of the frame, each outer skirt comprising an inflow edge secured to the frame and an outflow edge secured at intervals to the frame. The plurality of outer skirts may include a first outer skirt and a second outer skirt, wherein in the expanded configuration the first and second outer skirts include openings unsecured to the frame between the intervals. The inflow edge of the first annular outer skirt may be secured to the frame with sutures including radiopaque material. The first annular outer skirt may include radiopaque dye.

    摘要: 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.
