  • Patent number: 10849742
    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.

  • Patent number: 10799344
    Abstract: 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.

  • Publication number: 20200297482
    Abstract: An assembly can comprise a radially expandable and compressible annular frame, at least one linear actuator assembly coupled to the frame and at least one locking mechanism coupled to the frame. The linear actuator can be configured to apply a distally directed force and/or a proximally directed force to the frame to radially expand or compress the frame. The locking mechanism can comprise a first sleeve member connected to the frame at a first location, a second sleeve member having internal threads and being connected to the frame at a second location, and a first screw configured to engage the internal threads of the second sleeve member to retain the frame in a radially expanded state.

  • Publication number: 20200008937
    Abstract: 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.
