  • Patent number: 11951000
    Abstract: An implant and method for repairing and/or replacing functionality of a native mitral valve are in various embodiments configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor can be used to implant a prosthetic valve in a native mitral valve of a heart. The coiled anchor can include a plurality of ventricular turns and one or more atrial turns. The coiled anchor is configured to be implanted at the native mitral valve with the plurality of ventricular turns positioned in a left ventricle of the heart and around valve leaflets of the native mitral valve. The plurality of ventricular turns are configured such that when a radially outward pressure is applied to at least one of the plurality of ventricular turns, the coiled anchor is biased such that a first diameter of a first turn of the plurality of ventricular turns is expanded and a second diameter of a second turn of the plurality of ventricular turns is reduced.

  • Patent number: 11523899
    Abstract: A coiled anchor is positioned at a mitral valve by extending and deflecting a catheter such that a distal end portion of the catheter has a curved shape that is disposed in a left atrium and a distal end of the catheter is positioned near a commissure of the mitral valve. A ventricular portion of the coiled anchor is advanced from the catheter under the mitral valve at the commissure and into a left ventricle. An atrial portion of the coiled anchor is deployed in the left atrium by retracting the catheter off the atrial portion of the coiled anchor while maintaining the position of the ventricular portion of the coiled anchor in the left ventricle.

  • Patent number: 11234811
    Abstract: Systems and methods for replacing a native heart valve. An anchor comprises multiple coils adapted to support a heart valve prosthesis. At least one of the coils is normally at a first diameter, and is expandable to a second, larger diameter upon application of radial outward force from within the anchor. An expansible heart valve prosthesis is provided and is configured to be delivered into the anchor and expanded inside the multiple coils. This moves at least one coil from the first diameter to the second diameter while securing the anchor and the heart valve prosthesis relative to each other. The system further includes a seal on the anchor that can prevent at least some blood leakage after implantation of the heart valve prosthesis in the helical anchor. Additional apparatus and methods are disclosed.

  • Publication number: 20210137678
    Abstract: Prosthetic heart valves and anchors for use with such valves are provided that allow for an improved implantation procedure. In various embodiments, an anchoring device is formed as a coiled or twisted anchor that includes one or more turns that twist or curve around a central axis. One or more arms attached to the frame of the valve guide the anchoring device into position at the native valve as it exits the delivery catheter, and the expandable prosthetic valve is held within the coil of the anchoring device. The anchoring device and the valve can be delivered together, simplifying the valve replacement procedure.
