However, the geometry of natural valve is very complex and there are variety of parameters can affect performances of the valves. This study has simplified the geometry of natural valve so that there are only four parameters needs to be considered. The four parameters include the free edge angle, the minor-axis length, the vertical axis angle, and the open round. The study investigated the influence of these four parameters on biomechanics of the polyurethane prosthetic valves. On the other hand, we proposed silicone mold to produce PU heart valve. The method can significantly reduce the cost of PU valve production in the experimental stage.
