A coiled anchor for docking a mitral valve prosthesis at a native mitral valve of a heart has 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 coiled anchor includes a coiled core including a bio-compatible metal or metal alloy and having a plurality of turns extending around the central axis in a first position, and a cover layer around the core, the cover layer including a bio-compatible material that is less rigid than the metal or metal alloy of the coiled core.
