Metal biomaterials must be biocompatible; especially, when they contact directly with blood, they must be haemocompatible. Now, stainless steel, tantalum and nickel-titanium shape memory metal alloy are normally made into intravascular stands that are used to stretch blood vascular and resume blood circulation. Intravascular stand's haemocompatibility is very important because it directly influences the occurrence of thrombogenesis in blood system. This paper briefly reviews the metal intravascular stand's surface property, interface reaction with blood, structure design and the research of haemocompatibility.
