Groove carrying-type coating decomposable drug eluting stent

The invention discloses a groove carrying-type coating decomposable drug eluting stent, which comprises a stent main body and a drug coating, wherein the outer surface of the stent main body is provided with a drug-borne groove, the drug coating is coated in the drug-borne groove, and the drug coating comprises a biological decomposable polymer and an active drug. The drug eluting stent not only solves the combination problem between the coating and the stent, and improves the validity and the safety of the drug stent in the operation and application process, but also solves the restenosis and the late thrombosis inside the stent.
