Abstract
Methods of repairing the mitral valve and reducing mitral regurgitation. One method includes securing a first tissue anchor to a position on a posterior portion of the annular tissue of the mitral valve and a second tissue anchor to a position on an anterior portion of the annular tissue of the mitral valve. At least one tensile member spans between the first and second tissue anchors and across the orifice of the mitral valve. When tension is applied to the at least one tensile member, the posterior portion of the annular tissue is pulled toward the anterior portion.
Claims23
A method of repairing a mitral heart valve, the mitral heart valve having posterior and anterior leaflets forming an orifice therebetween, an annulus surrounding the posterior and anterior leaflets, and posterior and anterior commissures where the posterior and anterior leaflets join the annulus, the method comprising:
- (a) securing a first tissue anchor to a position on a posterior portion of the annulus between the posterior and anterior commissures;
- (b) securing a second tissue anchor to a position on an anterior portion of the annulus between the posterior and anterior commissures;
- (c) spanning at least one tensile member between the first and second tissue anchors and across the orifice of the mitral valve;
- and
- (d) applying tension to the at least one tensile member, thereby pulling the posterior portion of the annulus toward the anterior portion of the annulus.
A method of repairing a mitral heart valve, the mitral heart valve having posterior and anterior leaflets forming an orifice therebetween, an annulus surrounding the posterior and anterior leaflets, and posterior and anterior commissures where the posterior and anterior leaflets join the annulus, the method comprising:
- (a) directing a guide-wire into the left ventricle, across a position on a posterior portion of the annulus between the posterior and anterior commissures, through the left atrium, across a position on an anterior portion of the annulus between the posterior and anterior commissures, and returning to the left ventricle;
- (b) advancing a first tissue anchor along the guide-wire to the position on the anterior portion of the annulus;
- (c) securing the first tissue anchor to the position on the anterior portion of the annulus;
- (d) advancing a second tissue anchor along the guide-wire to the position on the posterior portion of the annulus;
- (e) securing the second tissue anchor to the position on the posterior portion of the annulus;
- spanning at least one tensile member between the first and second tissue anchors and across the orifice of the mitral valve;
- and
- (g) applying tension to the at least one tensile member, thereby pulling the posterior portion of the annulus toward the anterior portion of the annulus.
