A prosthetic device for sealing a native heart valves to prevent or reduce regurgitation comprises a spacer having one or more anchors. The spacer may also have atrial support structures, ventricular support structures, or both atrial and ventricular support structures In some cases, the spacer has anchors that attach to the leaflets as well as atrial and ventricular support. In some cases, the spacer straddles the annulus and is located by anchors, and in some cases the support structures can be implanted within the native heart valve. In some cases, the prosthetic device reduces the annulus diameter when implanted within the native heart vasculature. In some cases, the prosthetic device cinches the annulus when implanted within the native heart vasculature.

Tissue grasping devices and related methods

A clip for immobilizing leaflets of a cardiac or venous valve includes a hub having a pair of tangle resistant spring-biased outer arms coupled to an inferior end of the hub. A pair of tangle-resistant spring-biased inner arms lies adjacent to the outer arms and is coupled to a superior end of the hub. The clip may incorporate adjustable spacers and retrievable post implantation. A delivery catheter is used to position the valve clip adjacent a target valve while the outer and inner arms are biased in an opened position relative to each other. After the valve leaflets are located between the opened outer and inner arms, the biasing forces may be released to allow the clip to self-close over the valve leaflets.
