Abstract

Abstract Fe/Pd magnetic films were prepared by vacuum arc ion plating technology on 316L stainless steel vascular stents. The surface morphology, the surface roughness and the magnetism of coated stents were characterized by laser scanning confocal microscope and digital magnetic flux and field measuring instruments, while the biological effects of the Fe/Pd coated magnetic stents were evaluated through animals experiment. The results show that the Fe/Pd coated magnetic stents, which are smooth and which have good biological compatibility, significantly promote vascular endothelium regeneration, and inhibit tunica intima thickening and vascular wall inflammatory.
