Abstract
A stent is formed from a series of linked, radially aligned expandable rings. The end rings are formed of a radiopaque material while the rings positioned between the end rings are formed of a radio-transparent material. Two very bright fluoroscopic images are created by the end rings, without any compromise in the strength of the stent, while the center of the stent remains transparent so as not to obscure the image of lesion area when the stent is being centered therein.
