Implant heart valve devices, mitral valve repair devices and associated systems and methods
First Claim
1. A method of repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle, comprising:
- positioning a repair device in the left ventricle under the posterior leaflet and between a wall of the left ventricle and chordae tendineae; and
engaging an underside of the posterior leaflet with a support of the repair device such that a portion of the posterior leaflet moves toward the anterior leaflet,wherein, in the engaged arrangement, the repair device further includes a flap extending beyond an edge of the posterior leaflet toward the anterior leaflet.

Abstract
Systems, devices and methods for repairing a native heart valve. In one embodiment, a repair device for repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle comprises a support having a contracted configuration and an extended configuration, and an appendage, such as a flap or apron extending from the support. In the contracted configuration, the support is sized to be inserted under the posterior leaflet between a wall of the left ventricle and chordae tendineae. In the extended configuration, the support is configured to project anteriorly with respect to a posterior wall of the left ventricle by a distance sufficient to position at least a portion of the posterior leaflet toward the anterior leaflet, and the appendage is configured to extend beyond an edge of the posterior leaflet toward the anterior leaflet.

2. A method for repairing a native valve of a patient, the method comprising:
-
positioning a heart valve repair device in a subannular position behind at least one leaflet connected to chordae tendineae, the repair device having a support in an unexpanded configuration; and expanding the support in the subannular position such that the support engages an interior surface of a heart wall and a downstream-facing surface of the at least one leaflet, wherein the repair device is configured to reposition the at least one leaflet into an at least partially closed position and brace the at least one leaflet such that the function of the native valve is improved, wherein, in the expanded arrangement, the repair device further includes an appendage extending beyond an edge of the at least one leaflet toward another adjacent leaflet. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A method of repairing a native mitral valve having anterior leaflet and a posterior leaflet between a left atrium and a left ventricle, comprising
implanting a repair device having a support and an appendage under the posterior leaflet, wherein the support comprises an extension unit, and implanting the repair device under the posterior leaflet comprises implanting the extension unit under the posterior leaflet in an unexpanded state; - and
causing the support to press against a portion of an underside of the posterior leaflet and thereby push at least a portion of the posterior leaflet toward the anterior leaflet and extend the appendage beyond an edge of the posterior leaflet toward the anterior leaflet wherein causing the support to press against the underside of the posterior leaflet or engaging the underside of the posterior leaflet with the support comprises extending at least a portion of the extension unit such that the support presses against a wider portion of the posterior leaflet than in the unexpanded state. - View Dependent Claims (15, 16, 17, 18)

19. A method of repairing a native mitral valve having an anterior leaflet and a posterior leaflet between a left atrium and a left ventricle, comprising:
-
implanting a repair device having a support and an appendage under the posterior leaflet, wherein the support comprises a plurality of projections and a plurality of depressions, each depression being disposed between two of the projections, and causing the support to press against a portion of an underside of the posterior leaflet and thereby push at least a portion of the posterior leaflet toward the anterior leaflet and extend the appendage beyond an edge of the posterior leaflet toward the anterior leaflet, wherein causing the support to press against an underside of the posterior leaflet or engaging the underside of the posterior leaflet with the support comprises extending the projections along the underside of the posterior leaflet such that an upper side of the projections presses against the posterior leaflet and the chordae tendineae are positioned in at least some of the depressions.
