Publication number: 20190008632Abstract: 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 uyimain 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.Type: ApplicationFiled: July 2, 2018Publication date: January 10, 2019Applicant: THE CLEVELAND CLINIC FOUNDATIONInventors: Jose L.
