Abstract: Systems and methods for docking a heart valve prosthesis. A system can include an anchor formed as multiple coils adapted to support a heart valve prosthesis with coil portions positioned above and below the heart valve annulus. At least one of the coil portions can normally be at a first diameter and be expandable to a second, larger diameter upon application of radial outward force from within the helical anchor. Methods can include delivering an anchor, positioning and implanting a heart valve prosthesis, and expanding the heart valve prosthesis inside the anchor.

Abstract: Disclosed are devices and methods for providing simple, fast, effective, and repeatable anastomotic graft connections, which can reduce (or eliminate) risks associated with graft anastomoses, thus improving patient outcomes. An example embodiment is an anastomotic graft connection device that includes a connector and a cuff. The connector includes a first flared end and a second flared end. The first flared end is configured to be inserted into a vessel (e.g., blood vessel). At least the second flared end is configured to be attached to a graft. The cuff includes an inner ring and an outer ring. The inner ring is configured to secure the graft to at least the second flared end of the connector, and the outer ring is configured to exert force on the vessel to seal the first flared end of the connector against an inner wall of the vessel.

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.

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 first turn, a second turn, and a third turn. The coiled anchor is configured to be implanted at the native mitral valve with the second turn and the third turn positioned in a left ventricle of the heart and around the valve leaflets of the native mitral valve. The first turn is positioned in a left atrium of the heart such that the first turn is spaced apart from the native mitral valve. The coiled anchor is configured for positioning such that the first turn is the sole turn of the coiled anchor positioned in the left atrium.

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.

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 with a central turn that reduces in size upon implantation is used to approximate the amount of reduction in the size and the reshaping of the native mitral annulus to reduce valve leakage. A clip can be further applied to the native valve leaflets to reduce the size of the native mitral annulus and leakage therethrough. A prosthetic heart valve can be implanted in the coiled anchor to replace and further improve functionality of the valve. In some cases, the prosthetic valve can be implanted in a clipped valve, where the clip is detached from one of the native valve leaflets to provide space for the prosthetic valve to expand.

Abstract: A system including an anchor for docking a prosthetic valve at a native valve of a heart can have a first end, a second end, and a central axis extending between the first and second ends, and defines an inner space coaxial with the central axis. The valve prosthesis can include a protective layer or annular ring that surrounds a bottom edge of the second frame end. The protective layer or annular ring can include two layers, and the two layers can be different materials.

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.

Abstract: Systems and methods for replacing a heart valve. An expansible helical anchor is formed as multiple coils to support a valve prosthesis. At least one of the coils is expandable to a second, larger diameter upon application force from within the anchor.

This moves the coil from the first diameter to the second diameter while securing the anchor and prosthesis together. The system further includes a seal on the expansible heart valve prosthesis configured to engage the helical anchor and prevent blood leakage past the heart valve prosthesis after implantation of the heart valve prosthesis in the helical anchor.
