Abstract
An apparatus for repairing a heart valve and methods of use thereof are provided. The apparatus includes a radially expandable body and a blood-permeable member attached to the body at a first end and having at least one cord at a second end. The length or tension of the at least one cord is adjustable when the apparatus is implanted in a heart such that that the extent of atrial displacement of the heart'"'"'s mitral leaflets during ventricular contraction can be adjusted. To implant the apparatus in a heart, the apparatus is inserted into a retaining sheath and the retaining sheath is then inserted into the heart. The retaining sheath is retracted from the apparatus and the apparatus is positioned inside the heart. The length or tension of the at least one cord is adjusted to adjust the extent of atrial displacement of the heart'"'"'s mitral leaflets during ventricular contraction.
