  • Publication number: 20220287828
    Abstract: Anchoring or docking devices configured to be positioned at a native valve of a human heart and to provide structural support for docking a prosthetic valve therein. The docking devices can have coiled structures that define an inner space in which the prosthetic valve can be held. The docking devices can have enlarged end regions with circular or non-circular shapes, for example, to facilitate implantation of the docking device or to better hold the docking device in position once deployed. The docking devices can be laser-cut tubes with locking wires to assist in better maintaining a shape of the docking device. The docking devices can include various features to promote friction, such as frictional cover layers. Such docking devices can have ends configured to more securely attach the cover layers to cores of the docking devices.

  • Publication number: 20220257367
    Abstract: An implantable prosthetic valve can include a frame movable between a radially compressed and a radially expanded configuration. The frame can include a first strut having a first locking feature disposed on a radially facing inner surface of the strut and a second strut having a second locking feature disposed on a radially facing outer surface of the strut. The first and second locking features can engage each other so as to allow pivoting of the first and second struts relative to one another in a first direction upon radial expansion of the frame and resist pivoting of the first and second struts relative to one another in a second direction to resist radial compression of the frame.

  • Publication number: 20220110742
    Abstract: Various mechanically expandable prosthetic heart valves, as well as deliver apparatus, delivery assemblies, and methods for implanting such prosthetic heart valves. In one example, a prosthetic heart valve includes a mechanically expandable frame, a valve structure, and an actuator. The frame includes a plurality of struts and is movable between a radially compressed state and a radially expanded state. The valve structure includes a plurality of leaflets. The actuator is coupled to the frame and comprises an actuation lumen, a locking member, and a locking element. The actuation lumen is circumferentially spaced and axially parallel to the locking member. The actuation lumen is configured for receiving an axially movable actuation shaft that can move the frame between the radially compressed state and the radially expanded state. The locking element is rotatably coupled to the locking member and is configured to lock the frame at a desired state.

  • Publication number: 20220079750
    Abstract: A prosthetic heart valve has a frame including a plurality of strut members, an inflow end, and an outflow end. A leaflet structure is situated at least partially within the frame, and a covering is disposed around an exterior of the frame. The covering includes a cushioning layer, and a first strip member folded over an inflow circumferential edge portion of the cushioning layer to form a first protective portion. A second strip member is folded over an outflow circumferential edge portion of the cushioning layer to form a second protective portion. The first strip member and the second strip member are spaced apart from each other along a longitudinal axis of the prosthetic heart valve.

  • Patent number: 11185406
    Abstract: A prosthetic heart valve includes a frame having a plurality of strut members, an inflow end, and an outflow end. The prosthetic heart valve further includes a leaflet structure situated at least partially within the frame, and a covering disposed around the frame. The covering has a first layer and a second layer, wherein the second layer has a plush surface. The first layer is folded over a circumferential edge portion of the second layer to form a protective portion that extends beyond the strut members in a direction along a longitudinal axis of the prosthetic heart valve.

  • Publication number: 20210361417
    Abstract: A method of treating mitral valve stenosis in a human heart includes advancing a delivery apparatus through a right femoral vein, across a septal wall, and through a calcified mitral valve. A prosthetic heart valve is provided along a distal end portion of the delivery apparatus, wherein the prosthetic heart valve includes a metallic frame having a plurality of tissue-engaging elements positioned along an exterior surface and a leaflet structure for replacing the function of the calcified mitral valve. The prosthetic heart valve is radially expanded within an annulus of the calcified mitral valve such that at least some of the tissue-engaging elements of the prosthetic heart valve embed into the annulus. After radial expansion, the prosthetic heart valve is retained in position within the annulus via the tissue-engaging element and the leaflet structure replaces the function of the native mitral valve.

  • Patent number: 11083571
    Abstract: A prosthetic heart valve is radially collapsible to a collapsed configuration and radially expandable to an expanded configuration. The heart valve includes an annular inner frame formed with a plurality of angled first strut members, the inner frame being configured to foreshorten from a first length corresponding to the collapsed configuration to a second length corresponding to the expanded configuration. A leaflet structure is situated at least partially within the inner frame. An outer frame is disposed radially outward of the inner frame and coupled to the inner frame. The outer frame is configured to collapse with the inner frame and radially expand with the inner frame, and includes a plurality of second strut members. Portions of the second strut members are configured to bend radially outwardly into a curved shape as the inner frame and the outer frame move from the collapsed configuration to the expanded configuration.
