ABSTRACT:
A method of imposing a shape on an intact blood vessel other than a graft includes inserting a stent in the vessel. The stent includes a supporting portion which internally supports an interior wall of the vessel. The supporting portion includes a hollow tube, the walls of which have openings therein so that the interior wall of the vessel is exposed via the openings to fluid flow along the vessel. A central axis of the hollow tube forms a non-planar three dimensional at least partially helical shape. The hollow tube imposes the three-dimensional at least partially helical shape on the central axis of the vessel, inducing a swirling fluid flow within the stent supported part of the vessel.
