[The biocompatibility of Chinese nitinol alloy intravascular stent].
The aim of this study was to evaluate the biocompatibility of Chinese nitinol alloy intravascular stent. Sixteen Chinese nitinol alloy intravascular stents with 4 mm ID were implanted in the left and right iliac arteries of 8 normal dogs and were observed for one to six months. The results showed that the stents implanted were completely covered by a thin layer of the neointima after one month and the surface of neointima was covered by a monolayer of endothelium-like cells. These suggest that the Chinese nitinol alloy has very good biocompatibility.
