An interventional medical device and manufacturing method thereof. The interventional medical device comprises: a stent body (); a surface of the stent body () being provided with a drug releasing structure (), and drug in the drug releasing structure () 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.

Interventional medical device and manufacturing method thereof

A stent for a bifurcated vessel includes a stent body () with two open ends (). The stent body () includes multiple sets of annular units () having multiple undulating rods () and connecting rods () positioned between adjacent annular units () and used to connect the adjacent annular units (). At least one open end () of the stent body () has a slope structure.
