Nitinol superelasticity can be favorably used to design self-expending medical devices that can reduce the level of vessel injury associated with neointimal proliferation and thrombosis. This study was performed to compare the relative thrombogenicity of Nitinol surfaces prepared using various protocols (polished 600 grit and 1 μm finish, chemically-etched, heat treated and electropolished in two different electrolytes)…. Download the entire paper.
