Abstract
A spiral blood flow device includes a stent made up of a plurality of expansion members joined to a plurality of axial members that permit the stent to change diameter among a continuum of expanded configurations. The axial members have fixed orientation, whereas the expansion members have a variable orientation relative to the longitudinal axis throughout the continuum of expanded configurations. A spiral flow inducing structure, which may include fins attached to the axial members, define a helical flow angle that remains constant throughout the continuum of expanded configurations.
