1. A tissue restraining device comprising:
- an annuloplasty member for attachment to a valve annulus of a cardiac valve, the annuloplasty member defining an opening;
an anchor situated in a spaced relation to the annuloplasty member on an opposite side of the cardiac valve;
a plurality of restraining cords forming a restraining matrix extending from the annuloplasty member into the opening and toward the anchor; and
a tensioning strand extending distally from the restraining matrix, passing through the anchor, and extending proximally past the anchor so the restraining matrix is adjustable as a single unit to change a tension in the restraining matrix.

10. A method of treatment of a mitral valve comprising:
-
attaching an annuloplasty member substantially along the valve annulus; embedding an anchor into a tissue in a left ventricle; extending a restraining matrix from the annuloplasty member over a leaflet of the mitral valve, wherein a tensioning strand extends distally from the restraining matrix, through the anchor, and proximally past the anchor; and adjusting the restraining matrix to correct one or more prolapsing segments of the leaflet by changing a tension in the tensioning strand. - View Dependent Claims (11, 12, 13, 14, 15)
