Abstract

See full text

The present embodiments provide a valve for implantation in a patient, for example, an aortic valve. The valve comprises a proximal region comprising a cylindrical shape, and a distal region having a generally rectangular shape comprising opposing flat surfaces that are separated by narrower flat sides. A tapered region is disposed between the proximal and distal regions, where the tapered region comprises two opposing flat surfaces that transition into the opposing flat surfaces of the distal region. The opposing flat surfaces of the tapered region are angled relative to the proximal and distal regions. The opposing flat surfaces at the distal end of the valve allow fluid flow therethrough during antegrade flow and are generally adjacent to one another to inhibit blood flow through the valve during retrograde flow. Optionally, at least one reinforcement member may be coupled to the valve to prevent prolapse of the valve during retrograde flow.
