Abstract
Apparatus for regulating blood flow of a subject is provided, the apparatus comprising a prosthetic valve (20) that comprises a tubular element (22), shaped to define a lumen (23) therethrough, and a valve member (24), configured to be coupled to the tubular element (22) and to be disposed within the lumen (23). The prosthetic valve (20) has (1) a compressed configuration in which the lumen (23) has a compressed width, the valve member (24) is generally cylindrical, and the prosthetic valve (20) is configured to be percutaneously delivered into the subject, and (2) an expanded configuration in which the lumen (23) has an expanded width that is greater than the compressed width, and the valve member (24) is generally disc-shaped, is coupled to the tubular element (22), and is disposed within the lumen (23). Other embodiments are also described.

26. Apparatus for regulating blood flow of a subject, the apparatus comprising:
a transluminally-implantable ti king-disc valve, the tilting-disc valve comprising; a frame; defining an arrangement of cells that shape the frame as a tubular element having a first end and a second end; having a compressed state in which the frame is generally cylindrical, has a compressed width, and is transluminally deliverable into the subject, and having an expanded state in which the frame is generally cylindrical, has an expanded width that is greater than the compressed width, and defines a lumen between the first end and the second end; and a valve member; coupled to the frame, disposed within the lumen in both the compressed and expanded states of the first frame, having a compressed state, and having an expanded state in which the second frame; is disc-shaped, and provides directional fluid flow through the lumen by tilting in response to changes in relative fluid pressure between the first end and the second end, such that at least part of the valve member moves toward the first end and at least part of the valve member moves toward the second end. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
