Embodiment approach 1220

[0382] Any combination of fillers based on in-plane and out-of-plane nested leaf springs can be used. Combined with or without a blood-impermeable covering or barrier, this can be used to configure the embodiment to treat valve regurgitation. Additionally, multiple atrial and / or ventricular support structures, such as 1209, of various shapes and designs may be used.

[0384] Figure 122 and Figure 123 A crescent-shaped filler embodiment 1250 is shown with notches 1252, 1253 on either side. Figure 124 shows a schematic top view of a cross-section of the mitral valve, and Figure 125 A schematic view of the device 1250 inside the mitral valve is shown. Note that device 1250 may be any combination of flexible, elastic, rigid, solid, hollow, and / or compressible. For example, in one embodiment, the device 1250 can be straightened in length and compressed in height to allow for smaller diameter catheters.

Abstract

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, ventricularsupport 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 annulusdiameter when implanted within the native heart vasculature. In some cases, the prosthetic device cinches the annulus when implanted within the native heart vasculature.
