Percutaneously-deliverable mechanical valve
First Claim
1. Apparatus for regulating blood flow of a subject, the apparatus comprising a prosthetic valve, the prosthetic valve comprising:
- a first frame;
defining an arrangement of cells that shape the first frame as a tubular element having a first end and a second end;
having a compressed state in which the first frame is generally cylindrical, has a compressed width, and is transluminally deliverable into the subject, andhaving an expanded state in which the first 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 second frame;
coupled to the first frame,defining an arrangement of cells,having a compressed state in which the valve member is transluminally deliverable into the subject, andhaving an expanded state in which the second frame;
is disposed within the lumen, anddefines a valve member that provides directional fluid flow through the lumen by the second frame moving with respect to the first frame in response to changes in relative fluid pressure between the first end and the second end.

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.
