1. A method, comprising:
- positioning a delivery catheter adjacent a fiberous ring surrounding a heart valve;
positioning a receiving catheter adjacent the fiberous ring surrounding the heart valve, the receiving catheter having a coupling device;
passing a first piercing member and a first portion of a cord from the delivery catheter through the fiberous ring;
extending a first capture device from the receiving catheter;
capturing the first piercing member that extends through the fiberous ring with the first capture device;
passing a second piercing member and a second portion of the cord from the delivery catheter through the fiberous ring;
extending a second capture device from the receiving catheter;
capturing the second piercing member that extends through the fiberous ring with the second capture device;
connecting the first portion and the second portion of the cord with the coupling device to form a loop; and
releasing the loop and at least a portion of the coupling device from the receiving catheter.

11. A method, comprising:
-
positioning a delivery catheter adjacent a fibrous ring surrounding a heart valve; positioning a cord between at least a portion of chordae tendineae attached to leaflets of the heart valve with the delivery catheter; advancing the cord through the fibrous ring surrounding the heart valve; and modifying a configuration of the heart valve with the cord to induce the leaflets of the heart valve to coapt. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
