Abstract: Apparatus including a core is advanceable toward a patient's heart valve. The core tapers in a distal direction toward the smallest perimeter of the core. The apparatus includes a first ventricular arm, which is articulatable with respect to a first atrial arm at a first articulation site, and a second ventricular arm, which is articulatable with respect to a second atrial arm at a second articulation site. The articulation sites are adjacent to the smallest perimeter. The tapering of the core defines a minimum nonzero angle of the atrial arms with respect to a central longitudinal axis of the core. The first atrial arm and the first ventricular arm are arranged so as to clamp the first native leaflet. The second atrial arm and the second ventricular arm are arranged so as to clamp the second native leaflet. Other embodiments are also described.

Abstract: An apparatus for use with a prosthetic heart valve at a native heart valve comprises an adjustable-lumen prosthetic valve support. In a delivery state, the prosthetic valve support is transluminally deliverable to the heart. The prosthetic valve support is transitionable, within the heart, into an implantation state for implantation at the native valve. In the implantation state, the prosthetic valve support has an inner edge that defines a lumen through the prosthetic valve support, the lumen having a first diameter. After the prosthetic valve support is implanted at the native valve, the prosthetic valve support is transitionable into an enlarged state in which the lumen has a second diameter that is greater than the first diameter. In the enlarged state, the prosthetic valve support is configured to support, at the native valve, the prosthetic heart valve within the lumen.
