摘要:
An anchoring device that can be positioned within a native valve, such as the native mitral valve, to secure a replacement prosthetic valve in place. The anchoring device can comprise a docking station formed of a super elastic wire-like member defining a continuous, closed shape. The docking station can have an upper or atrial ring with at least two ring portions or half rings that are spaced apart across gaps. Descending bends from the ends of the two ring portions lead to a pair of anchors. The anchors can include oppositely-directed rounded V-shaped arms that extend generally parallel to the upper ring. When installed by a delivery device, the anchors can be located in the subvalvular space or the region/vicinity of the native leaflets and pinch the leaflets and the annulus against the upper ring which is located on the other side of the annulus.
