Mitral repair and replacement devices and methods

A system for repairing a native mitral valve of a heart, comprising:

• a coiled anchor, and a prosthetic valve;
• wherein the coiled anchor comprises:
• a plurality of ventricular turns;
• one or more atrial turns connected to the plurality of ventricular turns;
• wherein the ventricular turns and the atrial turns are covered by a biocompatible fabric;
• wherein 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;
• wherein the plurality of ventricular turns comprise a first ventricular turn and a second ventricular turn;
• wherein the first ventricular turn and the second ventricular turn are configured such that the first ventricular turn and the second ventricular turn have different unbiased sizes;
• wherein the prosthetic valve comprises:
• an expandable frame configured to be expanded in an inner space defined by the plurality of ventricular turns of the coiled anchor;
• a one way valve disposed within the expandable frame;
• and
• wherein the plurality of ventricular turns and the expandable frame are configured such that radially outward pressure applied to at least one of the plurality of ventricular turns due to expansion of the expandable frame causes the sizes of the first ventricular turn and the second ventricular turn to become the same.

A system for repairing a native mitral valve of a heart, comprising:

• a shape memory coiled anchor, a prosthetic valve, and a balloon;
• wherein the coiled anchor comprises:
• a plurality of ventricular turns that are configured to extend around leaflets of the native mitral valve;
• a single atrial turn connected to the plurality of ventricular turns;
• wherein the ventricular turns and the single atrial turn are covered by a biocompatible fabric;
• wherein 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;
• wherein the plurality of ventricular turns comprises a first ventricular turn and a second ventricular turn;
• wherein the first ventricular turn and the second ventricular turn are configured such that the first ventricular turn and the second ventricular turn have different unbiased sizes;
• wherein the prosthetic valve comprises:
• an expandable frame;
• a plurality of leaflets disposed within the expandable frame for controlling bloodflow through the prosthetic valve;
• and
• wherein the plurality of ventricular turns, the expandable frame, and the balloon are configured such that inflation of the balloon expands the expandable frame in an inner space defined by the plurality of ventricular turns of the coiled anchor and applies pressure to at least one of the plurality of ventricular turns to cause the sizes of the first ventricular turn and the second ventricular turn to become the same.
