Apparatus and methods for repairing the function of a diseased valve and method for making same

摘要

An apparatus for repairing the function of a diseased valve includes an annular first support member expandable to a first diameter. An annular second support member is spaced axially apart from the first support member and is expandable to a second diameter that is independent of the first diameter. A tubular graft section interconnects the first and second support members. The graft section defines an annulus having a third diameter that is independent of each of the first and second diameters. A prosthetic valve is secured within the annulus of the graft section. The bioprosthetic valve has at least two valve leaflets that are coaptable to permit the unidirectional flow of blood. Methods for repairing the function of a diseased valve and for making the apparatus are also provided.
