  • 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: 20210282757
    Abstract: Valvular implants and blood vessel closure devices herein are configured to be positioned in the heart and to block regurgitant blood flow from the heart into blood vessels supplying blood to the heart. The valvular implants can have a cover, a membrane, a valve, a resilient frame, and/or other features. Some valvular implants can have anchors to be positioned in the blood vessels, such as in pulmonary veins, and can anchor the implant to the heart wall. Various embodiments of covers and/or membranes act as valves contracting and expanding, to alternately permit and block blood flow. The valvular implants can cover one or more blood vessels, such as one, two, three, or four pulmonary veins, and can also be configured and implanted to block an appendage to the heart, such as the left atrial appendage.

  • Publication number: 20180055628
    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.
