Patent ID: 8591571

Claim:
A drug-eluting stent consisting essentially of: a stent body of a cylindrical configuration having outer and inner surfaces, the stent body being formed from a metallic material and a surface thereof being optionally activated with a surface treatment, and a coated layer coating at least the outer surface of the stent body, the coated layer being a single coated layer, a back surface of the coated layer contacting a surface of the metallic material and a front surface of the coated layer being configured to be in contact with blood, and the coated layer being prepared of a composition comprising a polymer and a drug, the composition not containing a lipid-soluble low-molecular weight compound at a ratio of 1 part by weight or more relative to 100 parts by weight of the polymer the drug being a vascular intimal hyperplasia inhibitor which does not inhibit proliferation of endothelial cells, the weight compositional ratio (Y/X) of the vascular intimal hyperplasia inhibitor (Y) based on the polymer (X) being within the range of 1/9 to 6/4, the polymer (X) being a copolymer of lactic acid (monomer A) and a terminal hydroxy straight alkyl carboxylic acid having 3 to 8 carbon atoms (monomer B), and the copolymerization mole ratio (A/B) of the monomer A and the monomer B being within the range of 8/2 to 2/8.
