Abstract:
A prosthetic valve comprises a valve body, comprising a tubular frame and a plurality of leaflets; an upstream support, comprising a second frame; and a flexible sheet that couples the upstream support to the valve body. The prosthetic valve is compressible into a delivery tool such that the prosthetic valve is in a compressed state in which the second frame and the tubular frame are arranged in series within the tool, and the valve body has a compressed body-diameter. The prosthetic valve is deployable from the tool such that the prosthetic valve automatically expands into an expanded state. In the expanded state, the second frame defines an inner perimeter, the sheet extends inwardly from the inner perimeter to the valve body, and the prosthetic valve defines a conduit through the upstream support and the valve body. Other embodiments are also described.

Claim (Index 189):
A method, comprising:\n introducing, into a subject, a prosthetic valve that includes:\n a valve body that includes a tubular frame, and a plurality of prosthetic leaflets arranged to facilitate upstream-to-downstream fluid flow through the prosthetic valve, \n an upstream support that includes a second frame that is distinct from the tubular frame; and \n a flexible sheet that couples the upstream support to the valve body; \n advancing the prosthetic valve to a heart of the subject while the prosthetic valve is in a compressed state in which:\n the second frame and the valve body are arranged in series within a delivery tool, and \n the valve body has a compressed body-diameter; and \n deploying the prosthetic valve at a mitral valve of the subject, such that the prosthetic valve defines a conduit through the upstream support and the valve body, by:\n expanding the valve body within the native valve, such that the valve body has an expanded body-diameter that is greater than the compressed body-diameter; and \n placing the upstream support against an upstream surface of the native valve by deploying the upstream support from the delivery tool such that:\n the upstream support becomes annular by expanding radially outward and deflecting with respect to the valve body, and \n the sheet extends inwardly from an inner perimeter of the second frame to the valve body.
