Abstract: Apparatus is provided, including: (A) a valve body (204) including a first frame (206) shaped to define a lumen therethrough, and a valve member (205) disposed within the lumen, (B) an upstream support (210), configured to be placed against an upstream surface of a native heart valve, and (C) a flexible sheet (214) that couples the upstream support to the valve body. The valve body has a compressed state in which the first frame has a first diameter, and an expanded state in which the first frame has a second diameter that is greater than the first diameter. The support includes a second frame (212) that has a compressed state, and an expanded state in which the second frame is annular, has an inner perimeter that defines an opening through the second frame, and has an outer perimeter. Other embodiments are also described.

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.
