  • Patent number: 10973634
    Abstract: In one embodiment, a delivery apparatus handle, such as for a mechanical heart valve frame can comprise an actuation knob with a toggle mechanism that can toggle the actuation knob from a first state in which the actuation knob is operable to cause the linear or rotational movement of multiple elements or sets of elements, such as tubes that are attached to, e.g., a mechanical heart valve frame to cause expansion or collapsing of the frame, to a second state in which only a single element or set of elements is moved, allowing for additional operations, such as, e.g., locking the frame and/or releasing it from the delivery apparatus.

  • Patent number: 10973639
    Abstract: A system for implanting a repair device onto a native valve of a natural heart to repair the native valve of a patient during a non-open-heart procedure. The system includes a base assembly, a pair of paddles, and a pair of gripping members. The base assembly includes a shaft and a coupler attached to the shaft such that the coupler can be moved along the shaft. The paddles are movable between an open position, a closed position and a bailout position. The paddles and the gripping members are configured to attach to the native valve of the patient. Movement of the coupler along the shaft causes the paddles to move between the open position, the closed position, and the bailout position.

  • Patent number: 10966822
    Abstract: A method for manufacturing a heart valve using bioprosthetic tissue that exhibits reduced in vivo calcification. The method includes applying a calcification mitigant such as a capping agent or an antioxidant to the tissue to specifically inhibit oxidation in tissue. Also, the method can be used to inhibit oxidation in dehydrated tissue. The capping agent suppresses the formation of binding sites in the tissue that are exposed or generated by the oxidation and otherwise would, upon implant, attract calcium, phosphate, immunogenic factors, or other precursors to calcification. In one method, tissue leaflets in assembled bioprosthetic heart valves are pretreated with an aldehyde capping agent prior to dehydration and sterilization.

  • Patent number: 10966827
    Abstract: A method of implanting a prosthetic mitral valve includes advancing a delivery apparatus into a left side of a patient's heart and deploying a support structure from the delivery apparatus. The support structure extends around native mitral valve leaflets such that the native leaflets are disposed radially within the support structure. The method also includes advancing a prosthetic heart valve within the native leaflets. The prosthetic heart valve is separate from the support structure and includes an annular frame and a valve structure positioned within the annular frame, and prosthetic heart valve is in a radially collapsed configuration. The method further includes expanding the prosthetic heart valve from the radially collapsed configuration to a radially expanded configuration. In the radially expanded configuration, the annular frame of the prosthetic heart valve engages the native leaflets and is separated from the support structure by the native leaflets.

  • Patent number: 10966711
    Abstract: Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

  • Publication number: 20210093450
    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.
