Method of Treating Paravalvular Leakage After Prosthetic Valve Implantation
First Claim
1. A method for treating paravalvular leakage at a location of a prosthetic valve comprising 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.

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.

12. A method of implanting a prosthetic valve and treating paravalvular leakage comprising the steps of:
-
tracking a prosthetic valve delivery system to the native mitral valve in a radially compressed configuration for delivery; deploying the prosthetic valve at the native mitral valve; detecting paravalvular leakage at the prosthetic valve implantation site; delivering a clip to a location adjacent chordae tendinae of the native mitral valve; and deploying the clip such that the clip captures at least some of the chordae tendinae of the native mitral valve, thereby increasing tension in the captured chordae tendinae. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
