Abstract
A method for treating paravalvular leakage at a location of a stented prosthetic valve includes the steps of delivering a clip to a location adjacent chordae tendinae of a native valve, and deploying the clip such that the clip captures at least some of the chordae tendinae of the native valve, thereby increasing tension in the captured chordae tendinae. The clip is delivered to the location in a collapsed stated and is released from a sheath convert to an undeflected or relaxed state. After the clip is released from the sheath, the clip is rotated to capture the chordae tendinae. The clip is then released from the delivery system and the delivery system is retracted.
