Apparatus and method for replacing a diseased cardiac valve
First Claim
1. An apparatus for replacing a diseased cardiac valve, said apparatus being movable from a radially collapsed configuration to a radially expanded configuration, said apparatus comprising:
- an expandable support member having a first end portion, a second end portion, and a main body portion extending between said first and second end portions, said main body portion including an outer circumferential surface and a circumferential axis extending about said outer circumferential surface; and
a prosthetic valve secured within said main body portion of said expandable support member;
said main body portion including a plurality of wing members spaced apart from one another by an expandable region, each of said wing members including a first end portion, a second end portion, and a flexible middle portion extending between said first and second end portions, wherein the second end portion of each of said wing members is integrally formed with said main body portion at a base of the second end portion of each of said wing members;
said first end portion of each of said wing members being adjacent said circumferential axis and substantially flush with said outer circumferential surface when said apparatus is in the radially collapsed configuration;
said first end portion of each of said wing members extending substantially radial to said outer circumferential surface when said apparatus is in the radially expanded configuration.

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.
