Abstract

An epicardial clip for reshaping the annulus of the mitral valve of a heart includes a curved member having an anterior segment configured to be positioned in the transverse sinus of the heart, a posterior segment configured to be positioned on the posterior side of the heart, such as on or inferior to the atrioventricular groove, and a lateral segment extending between the anterior segment and the posterior segment. The lateral segment includes a curve such that the first end of the member is positioned at or above the plane of the mitral valve and the second end of the member is positioned at or below the plane of the mitral valve.

Claims

1. A method of epicardial treatment of mitral regurgitation associated with the mitral valve of a heart, the anatomy of the heart including an aorta, a pulmonary trunk, a superior vena cava, a transverse sinus, a left atrial appendage, and an oblique sinus, the method comprising:

providing a clip having an anterior segment, an anterior end, a posterior segment, a posterior end and a lateral segment extending between the anterior segment and the posterior segment;

positioning the anterior segment in the transverse sinus of the heart; and

positioning the posterior segment on or inferior to the atrioventricular groove of the heart;

wherein the clip reshapes the annulus of the mitral valve; and

wherein said anterior and posterior ends are spaced apart from one another and remain separated by a gap or opening after said positionings and remain spaced apart, separated by said gap or opening while said clip reshapes the annulus.

2. The method of claim 1, wherein the posterior segment applies pressure on the posterior wall of the left ventricle, improving coaptation of the mitral valve.

3. The method of claim 1, wherein the lateral segment extends around a lateral side of the heart below the left atrial appendage of the heart.

4. The method of claim 1, wherein the lateral segment extends around a lateral side of the heart above the left atrial appendage of the heart.

5. The method of claim 1, wherein the mitral valve lies in a plane, and wherein the anterior segment extends above the plane of the mitral valve.

6. The method of claim 1, wherein the mitral valve lies in a plane, and wherein the posterior segment extends below the plane of the mitral valve.

7. The method of claim 1, further comprising a pad extending from the clip, wherein the pad applies pressure on the posterior wall of the left ventricle, improving coaptation of the mitral valve.
