Abstract: A prosthetic valve includes a tubular valve body, snares, and an upstream support. A native valve of a heart of a subject is disposed between an atrium and a ventricle of the heart, and has an annulus and leaflets. The prosthetic valve is advanced to the heart while in a compressed state. The prosthetic valve is positioned within the heart such that the snares are disposed upstream of the annulus and leaflets. The snares are expanded radially outwardly upstream of the leaflets. Subsequently, the prosthetic valve is moved in a downstream direction such that the snares become disposed downstream of the leaflets. While the snares remain downstream of the leaflets, the upstream support is expanded within the atrium, and the upstream support is placed against an upstream surface of the annulus. Other embodiments are also described.

Abstract: A prosthetic heart valve implant is provided including a frame shaped so as to define upstream and downstream openings at upstream and downstream ends of the frame, respectively, when the implant is in an expanded state for implantation at a heart native valve. A sheet is coupled to the frame. When the implant is in the expanded state, the frame is shaped so as to define the following longitudinal portions arranged along a central longitudinal axis of the prosthetic heart valve implant: a substantially cylindrical mid portion having a diameter greater than respective diameters of the upstream and the downstream ends of the frame; an upstream portion, extending upstream and radially inward from the mid portion; and a downstream portion, extending downstream and radially inward from the mid portion. Other embodiments are also described.

Abstract: A rod (508) is transfemorally advanceable to the heart. An implant (460) comprises (i) a first frame (462), compressed around a first longitudinal site of a distal portion of the rod, (ii) a second frame (464), compressed around a third longitudinal site of the distal portion, (iii) a valve member (50), disposed within the second frame, and (iv) a flexible sheet (466), coupling the first frame to the second frame, and disposed around a second longitudinal site of the distal portion, the second longitudinal site being between the first longitudinal site and the third longitudinal site. An extracorporeal controller (569) is coupled to a proximal portion of the rod, and is operably coupled to the distal portion of the rod. Operating the controller bends the distal portion of the rod causing articulation between the frames. Other embodiments are also described.
