Patent attributes
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.
