摘要:
A flow diverter is described and fabricated using ultra-thin porous thin-film Nitinol, and is configured for implantation to a treatment site within a vessel for significant reduction in an intra-aneurismal flow velocity and vorticity. Using small size pores in a coverage area of only 10%, a 90% reduction in flow velocity into a pseudo-aneurysm can be achieved, with an almost immediate cessation of flow into an anatomical feature such as aneurysm sac in vivo. The size of the holes can be tailored to be any shape and range in size from 1-400 μm using photolithography and from 5-1000 nm using ebeam lithography.
