摘　　要：Coronary stent is used to treat stenosis artery by recovering the luminal diameter of artery and maintaining the normal blood flow. The geometry of coronary stent is an important factor for the radial force. In this study,the relation between the radial force of stent and crown angle was discussed. The result showed that there was no particular rule between the radial force of stent and the crown angle. The maximum radial force of stent was obtained when the crown angle was 50. 04° and the minimum radial force was got when the crown angle was 75°.Coronary stent is used to treat stenosis artery by recovering the luminal diameter of artery and maintaining the normal blood flow.
