Abstract
The present invention is directed to a radial expandable stent for use in blood vessels. The length of the stent after expansion is substantially the same as the stent length before expansion. The stent is annealed at high temperatures to permit the wire to form an original multi-loop design including a plurality of concentric bended loops in a continuous wire folded along a length thereof. This provides desired alignment of the stent in the blood vessel in order to enhance desired blood flow and thereby reduce thrombogenicity.
