    摘要: An interventional medical device and manufacturing method thereof. The interventional medical device comprises: a stent body (1); a surface of the stent body (1) being provided with a drug releasing structure (3), and drug in the drug releasing structure (3) being drug for suppressing proliferation of adventitial fibroblasts and a drug for suppressing proliferation of intimal and/or smooth muscle cells. In use, after interventional medical device is implanted into a human body, the drug for suppressing proliferation of adventitial fibroblasts carried thereon can promote the compensatory expansion of the vessel, and the drug for suppressing proliferation of intimal cells and/or smooth muscle cells carried thereon can suppress intimal proliferation of the vessel. The combination of the two kinds of drugs greatly reduces the occurrence rate of in-stent restenosis.
