Abstract

The stent structure of the present invention would utilize an annular base ring defining an inflow orifice, with at least two circumferentially-spaced posts molded into the annular base ring at one end, and at their upper ends, molded into an upper ring comprising at least bi-segmented parabolic shaped scallops. The posts, which are constructed of spring steel molded in place, would provide the flextral capability necessary to allow relative movement between the scallops of the upper ring and the annular base. The parabolic-shaped segments taken together form a right cylinder of the inside diameter of the valve. The parabolic shape of the scallops reduce stress on the valve cusps.
