STENT FOR PERCUTANEOUS CORONARY INTERVENTION, COATED WITH VASCULAR RESTENOSIS PREVENTION DRUG

摘要

A stent for percutaneous coronary intervention, which is coated with a vascular restenosis prevention drug,is provided. The stent includes a plurality of struts. Here, minute wells are formed on the surface of each ofthe struts by scarring a surface of each of the struts, and the entire surface of each of the struts including thewells is coated with a vascular restenosis prevention drug. Since the stent is coated with a vascular restenosis prevention drug and a considerable amount of the vascular restenosis prevention drug is also contained in eachof the drug containing grooves and the drug containing holes, it is possible to provide a brilliant anti-restenosis effect for at least a certain period of time when restenosis is very likely to occur by slowly releasing the vascular restenosis prevention drug into blood vessel wall.
