Described herein is a system and method for reducing the risk of late thrombosis associated with drug eluting stent therapy. The stents described herein have polymeric blend coatings that can be tailored to have specific degradation times once implanted into the vasculature. The polymeric blends can have at least two polymers with different weight average molecular weights, thereby giving them degradation times that can tailored depending on the weight average molecular weights of the various polymers in the blend. The coatings can have bioactive agents dispersed on or within them which can be eluted in sync with the degradation time of the blended polymeric coating.
