Polydioxanone(PDS),one of the bioabsorbable materials for coronary stent,is catching eyes of researchers recently. When designing the geometry of the PDS coronary stent,the length and the height of the crown are quite important. However,rarely literatures have discussed the relationship between the two geometry parameters and the radial force of the bioabsorbable coronary stent. Therefore,a current effective tool of finite element method was applied in the evaluation of the relationship. By simulating 4 groups of models,it was obtained that the radial force of the coronary stent would not definitely increase with the rising value of Lcrownfrom 0. 8 mm to 2. 4mm. Meanwhile,Hcrownand radial force of the coronary stent had no linear relationship with each other. 相似文献
