Abstract
A cannula cut spiral flow inducing stent includes a plurality of spiral inducing flow diverters that each include a piece of sheet metal with a helically shaped flow surface. A proximal stent region, which includes a plurality of first struts, is joined to a proximal end of each of the spiral inducing flow diverters. A distal stent region, which includes a plurality of second struts, is joined to a distal end of each of the spiral inducing flow diverters. All of the first struts and all of the second struts share a cannula thickness, but the shaped pieces of sheet metal may have a lesser thickness.
