[The biocompatibility of Chinese nitinol alloy intravascular stent]
1Department of Cardio-thoracic Surgery, Zhujiang Hospital, First Military Medical University, Guangzhou 510282.
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.
