Radioactive stents is a promising avenue to reduce the rate of restenosis after percutaneous transluminal coronary angioplasty (PTCA). In this paper

the preparation methods of radioactive stents including ion implantation

activation in reactor or in cyclotron and surface handling methods were reviewed. Ion implantation was used to produce the 32 P-implanted stent undergoing clinic evaluation. Other methods also showed their respective advantages. The composit polymer stent or nitinol stent may be the next aims to be explored in this field.
