Heart valve repair apparatus and methods
First Claim
1. A method for implanting an annuloplasty device and repairing a mitral valve, the mitral valve having a valve annulus, the valve annulus having an annulus anterior portion and an annulus posterior portion, the annulus posterior portion and the annulus anterior portion defining a mitral valve opening therebetween, the annulus posterior portion having a generally arcuate shape, the mitral valve having an anterior valve leaflet attached to the annulus anterior portion and a posterior valve leaflet attached to the annulus posterior portion, the anterior and posterior leaflets having respective anterior and posterior free margins, the anterior and posterior leaflets movable between a closed systolic configuration in which the free margins are in an approximated spatial relationship, and an open diastolic configuration in which the free margins are spaced apart to allow blood flow through the mitral valve opening generally along a valve-flow axis;
- the annuloplasty device comprising an anterior section and a posterior section coupled to the anterior section, the posterior and anterior sections divided along a first axis, the annuloplasty device having a maximum width dimension along the first axis, the posterior section having a generally curvilinear shape and including a permanent deformation such that the posterior section is non-planar with respect to the anterior section when viewed in a direction generally parallel to the first axis; and
wherein the method comprises;
i) attaching the anterior section of the annuloplasty device to the annulus anterior portion, andii) attaching the posterior section of the annuloplasty device to the annulus posterior portion such that the permanent deformation is retained after attachment of the anterior and posterior sections to the annulus thereby fixing the annulus posterior portion into a non-planar configuration to improve coaptation of the leaflet free margins in the systolic configuration.

Abstract
Valve repair apparatus and methods for ensuring proper coaptation and operation of the leaflets of a heart valve. Main aspects of the disclosure relate to devices including a support member configured for attachment to the heart valve annulus, a post extending from the support member away from the plane of the annulus and a connector coupled with the post and configured for attachment to at least one of the leaflets. The various embodiments may include a replacement heart valve connected with the support member for facilitating full replacement as opposed to near repair of an existing native heart valve. Various other devices include support structure and one or more posts connected to opposite sides of the support structure and extending from one side of the valve annulus to another to modify the shape of the annulus.

7. A method for implanting an annuloplasty device and repairing a mitral valve, the mitral valve having a valve annulus, the valve annulus having an annulus anterior portion and an annulus posterior portion, the annulus posterior portion and the annulus anterior portion defining a mitral valve opening therebetween, the annulus posterior portion having a generally arcuate shape, the mitral valve having an anterior valve leaflet attached to the annulus anterior portion and a posterior valve leaflet attached to the annulus posterior portion, the anterior and posterior leaflets having respective anterior and posterior free margins, the anterior and posterior leaflets movable between a closed systolic configuration in which the free margins are in an approximated spatial relationship, and an open diastolic configuration in which the free margins are spaced apart to allow blood flow through the mitral valve opening generally along a valve-flow axis;
-
the annuloplasty device comprising an anterior section and a posterior section coupled to the anterior section, the posterior and anterior sections divided along a first axis, the annuloplasty device having a maximum width dimension along the first axis, the posterior section having a generally curvilinear shape and including permanent deformations such that the posterior section is non-planar with respect to the anterior section when viewed in a direction generally parallel to the first axis and such that a portion of the posterior section is deformed inwardly toward the anterior section; and
wherein the method comprises;i) attaching the anterior section of the annuloplasty device to the annulus anterior portion, and ii) attaching the posterior section of the annuloplasty device to the annulus posterior portion such that the permanent deformations are retained after attachment of the anterior and posterior sections to the annulus thereby fixing the annulus posterior portion into a non-planar configuration and moving the annulus posterior portion inwardly toward the annulus anterior portion to improve coaptation of the leaflet free margins in the systolic configuration. - View Dependent Claims (8, 9, 10, 11, 12)
