Abstract
An apparatus for replacing a diseased cardiac valve is movable from a radially collapsed configuration to a radially expanded configuration. The apparatus comprises an expandable support member and a prosthetic valve secured therein. The main body portion extends between first and second end portions and includes an outer circumferential surface, a circumferential axis extending about the circumferential surface, and a plurality of wing members spaced apart from one another by an expandable region. Each of the wing members includes first and second end portions and a flexible middle portion extending between the end portions. The second end portion is integrally formed with the main body portion. The first end portion is adjacent the circumferential axis and substantially flush with the outer circumferential surface in the radially collapsed configuration. The first end portion extends substantially radial to the outer circumferential surface in the radially expanded configuration.

15. A method for replacing a diseased cardiac valve, said method comprising the steps of:
-
providing an apparatus, the apparatus comprising an expandable support member and a prosthetic valve secured within a main body portion of the expandable support member, the main body portion including an outer circumferential surface, a circumferential axis extending about the circumferential surface, and a plurality of wing members spaced apart from one another by an expandable region, each of the wing members including a first end portion, a second end portion, and a flexible middle portion extending between the first and second end portions, the second end portion of each of the wing members being integrally formed with the main body portion; placing the expandable support member, in a radially collapsed configuration, about an inflatable member; loading the apparatus into a delivery catheter; advancing the delivery catheter to the diseased cardiac valve; and deploying the apparatus, in a radially expanded configuration, so that the first end portion of each of the wing members extends substantially radial to the outer circumferential surface, thereby contacting cardiac tissue and securing the apparatus in place of the diseased cardiac valve. - View Dependent Claims (16, 17, 18, 19, 20)
