Research on micro-structure and hemo-compatibility of the artificial heart va…

Abstract. In order to seek the method to improve the hemo-compatibility of artificial mechanical heart valve, the surface of rabbit’s heart valve was observed using the scanning electron microscopy (SEM). The results showed that the dual-scale structure which consists of cobblestones-like structure of 8 umin underside diameter and 3 um in height, and the fine cilia of about 150 nm in diam…
