摘要: Equiatomic nickel-titanium (NiTi) or Nitinol possess a unique combination of properties, including superelasticity and shape memory, which are very attractive for biomedical applications. NiTi has been used in orthopedic orthodontic implants several decades contributed to significant improvements these fields [1, 2]. This alloy is rapidly becoming the material choice selfexpanding stents, graft support systems, filters, baskets various other devices minimally invasive interventional procedures (Fig. 1) [1,3]. While superior performance over conventional engineering materials well documented [1,4,5], high nickel content (55 weight % Ni) itspossible influence on biocompatibility continues be an issue concern. concern further complicated by conflicting literature corrosion resistance.
