Abstract

The present invention relates to an improved bioresorbable polymeric vascular stent device (100) or patterns having least recoil and flexible enough to allow crimping and expansion for supporting and maintaining the patency of a body lumen. In particular, the invention relates to stent pattern of bioresorbable and biocompatible polymer which fits within the body lumen namely blood vessels and is useful in treating various cardiovascular disorders like atherosclerosis, restenosis or cannanlicular obstructions. It also relates to delivering the drug via stent scaffold to adjacent vessel wall through a unique technology which leads to uniform distribution of drug particles within the polymeric stent scaffold.
