Title (EN) STENT FOR PERCUTANEOUS CORONARY INTERVENTION, COATED WITH VASCULAR RESTENOSIS PREVENTION DRUG
(FR) STENT POUR INTERVENTION CORONARIENNE PERCUTANEE ENROBE D'UN AGENT DE PREVENTION DES RESTENOSES
Abstract:
(EN) 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.
(FR) L'invention porte sur un stent pour interventions coronariennes percutanées, enrobé d'un agent de prévention des resténoses comprenant une série de segments à la surface desquels sont formés des mini-alvéoles et des rainures. La totalité de la surface des segments dont les alvéoles et les rainures étant revêtue dudit agent, il produit de par sa quantité élevée en s'instillant lentement dans la paroi du vaisseau sanguin, un fort effet anti-resténose, au moins pendant la période ou les probabilités de resténose sont élevées.
