Abstract
An intravascular stent is configured for asymmetrical differential deployment and to align with a fibrous cap to treat vulnerable plaque. The stent is configured so that reduced expansion forces are imparted during deployment to the fibrous cap, thereby reducing the likelihood of cap rupture. The stent includes cylindrical rings connected by links and a cover attached to a portion of the stent to differentially restrict stent expansion when the stent is expanded from a delivery diameter to an implanted diameter thereby creating asymmetrical circumferential deployment. The portion of the stent having the cover imparts lower expansion forces from the stent expansion onto the fibrous cap area than other portions of the stent not having the cover.
