ABSTRACT:
A radioisotope stent that is made radioactive for most of the stent's length at a center section of the stent, but is not radioactive for a limited length at each end section of the stent. Such a stent design would have a negligible radiation level at the extreme ends of the stent. Therefore, there will not be any portion of the dilated stenosis that has no mechanical support from the stent and is also exposed to a moderate level of radiation. Furthermore, all portions of the dilated stenosis that are exposed to a high or moderate level of radiation will be mechanically supported by the stent so as to preclude the phenomena of late vascular contraction. Thus it is an object of this invention to have a stent that is designed with a comparatively high level of radioactivity at a longitudinally central section of the stent and would be free of any radioactivity at each of the two end sections of the stent.
