Patent ID: 8641756

Claim:
A stent comprising: a stent body of a cylindrical configuration having outer and inner surfaces with a diamond-like thin film coated on the surfaces; a first coated layer coating at least the outer surface of the stent body, the first coated layer being prepared of a first composition comprising a polymer and a vascular intimal hyperplasia inhibitor of a kind, which does not inhibit proliferation of endothelial cells, the inhibitor being selected from the group consisting of ximelagatran, melagatran, dabigatran and dabigatran etexilate, and being micro-dispersed in crystal state with particles in a nanometer or submicron order in the first composition, the weight compositional ratio of the polymer to the vascular intimal hyperplasia inhibitor being within the range of 8:2 to 3:7; and a second coated layer coating substantially completely over the first coated layer, the second coated layer being prepared of a polymer alone or a second composition comprising a polymer and a drug, the weight compositional ratio of the drug being less than 20% by weight of the composition.
