Abstract: A prosthetic heart valve may include a stent having an inflow end, an outflow end, a collapsed condition, and an expanded condition. The prosthetic valve may also include a collapsible and expandable valve assembly disposed within the stent and having a plurality of leaflets. The prosthetic valve and/or stent may include features to anchor the prosthetic valve to a native valve annulus and to seal the prosthetic valve with respect to the native valve annulus, such as planar and/or nonplanar annular sealing members coupled to ends of the stent. The stent may include one or more circumferential rows of anchor members or hooks extending radially outwardly from the stent. These hooks may be configured to extend in a particular direction when the stent is in the collapsed condition to facilitate resheathing of the stent if, upon deployment, a user determines the prosthetic heart valve is not positioned optimally.

Abstract: A device for transcatheter gathering of tissue of a heart valve leaflet may include an elongated tube, a capture tool moveable in the tube between a retracted position and an extended position, a tissue support located within a distal portion of the tube, and a clamping member pivotable in the tube between an open position spaced from the tissue support and a closed position adjacent the tissue support. The clamping member may have a flattened clamping portion and a C-shaped portion that defines a pocket therein. An open side of the C-shaped portion may face the tissue support. The capture tool and the clamping member may be operable to gather and clamp tissue between the tissue support and the clamping member, such that the clamped tissue has a gathered configuration. The device may also include a releasable clip adapted to hold the clamped tissue in the gathered configuration.

Abstract: A prosthetic heart valve includes stabilization features for anchoring the prosthetic heart valve within a native valve annulus. The prosthetic heart valve includes an expandable stent having an inflow end and an outflow end, and a valve assembly disposed within the stent. One such stabilization feature is a collapsible and an expandable frame formed of compliant wires. The frame has a body including a first end coupled to the stent, a second end, and a lumen extending therethrough for receiving the stent and the valve assembly. When the frame is expanded in the native valve annulus, the compliant wires form an indented region in the frame between the first and second ends of the body and a sub-annulus portion of the frame forms a bulge.
