Abstract: A transcatheter valve prosthesis includes an expandable tubular stent, a prosthetic valve within the stent, and an anti-paravalvular leakage component coupled to and encircling the tubular stent. The anti-paravalvular leakage component includes a radially-compressible annular scaffold, which is a sinusoidal patterned ring of self-expanding material, and an impermeable membrane extending over the annular scaffold. The anti-paravalvular leakage component has an expanded configuration in which at least segments of the annular scaffold curve radially away from the tubular stent. Alternatively, the anti-paravalvular leakage component includes a plurality of self-expanding segments and an annular sealing element coupled to inner surfaces of the segments. The anti-paravalvular leakage component has an expanded configuration in which the segments curve radially away from the tubular stent and the annular sealing element is positioned between an outer surface of the tubular stent and inner surfaces of the segments. The segments may be orthogonal or oblique to the outer surface of the tubular stent.

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.
