Systems and methods of atrioventricular valve replacement are provided. In various embodiments, an arch-like support structure is provided that is insertable and implantable into a heart and is positioned in the mitral annulus to replace a native mitral valve. The support structure is operable to support, and various systems comprise leaflet and chord structures operable to control and regular blood flow between chambers of the heart.

The present invention relates to mitral valve repair and replacement devices and methods. An implant and method for repairing and / or replacing the function of a native mitral valve, in various embodiments, is configured to reduce or eliminate mitral regurgitation and residual mitral valve leakage. A coiled anchor with a central turn that reduces in size after implantation is used to approximate the native mitral annulus size and reshape 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 reduce leakage therethrough. An artificial heart valve can be implanted in the coiled anchor to replace and further improve the function of the valve. In some cases, an artificial valve can be implanted in the clipped valve, with the clip detached from one of the native valve leaflets to provide space for the artificial valve to expand.

The present application relates to a multi-part replacement heart valve prosthesis. The replacement mitral valve prosthesis includes a support structure and a valve body having three flexible leaflets. The support structure preferably includes an inner valve frame and an outer sealing frame. The valve frame supports the flexible leaflets. The sealing frame is adapted to conform to the shape of a native mitral annulus. The sealing frame can be coupled to an inlet end of the valve frame, an outlet end of the valve frame, or both. A plurality of anchors are coupled to the outlet end of the valve frame. The anchors extend radially outward to be disposed behind native leaflets. The prosthesis preferably includes a skirt disposed along an exterior of the outer sealing frame. The prosthesis is collapsible for delivery into the heart by a delivery catheter. The prosthesis is configured to self-expand for deployment in the heart upon release from the delivery catheter.
