Abstract: 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.

Abstract: A stent for a bifurcated vessel includes a stent body (1) with two open ends (5, 6). The stent body (1) includes multiple sets of annular units (2) having multiple undulating rods (4) and connecting rods (3) positioned between adjacent annular units (2) and used to connect the adjacent annular units (2). At least one open end (6) of the stent body (1) has a slope structure.

Abstract: An interventional medical device and manufacturing method thereof, the interventional medical device comprising a stent body (1); the stent body (1) is provided with a drug releasing structure on the surface, the drug in the drug releasing structure being a drug for inhibiting adventitial fibroblast proliferation. When the interventional medical device is implanted into a human body, the drug for inhibiting the adventitial fibroblast proliferation can be slowly released into vessel wall cells in contact with the stent body (1), thus inhibiting the proliferation of the adventitial fibroblasts, promoting vascular compensatory expansion, and reducing the incidence rate of instent restenosis.

Abstract: A stent for a bifurcated vessel comprises a stent body having two open ends, wherein at least one of the open ends of the stent body is a wedge structure, a second opaque marker is provided on the two ends of the slant long axis of the wedge structure, the stent body is provided with two first opaque markers, and the connecting line between the two first opaque markers is parallel to the slant of the wedge structure. When the two first opaque markers overlap with each other, the slant of the wedge structure of the stent for a bifurcated vessel is precisely positioned during implantation so that the slant of the wedge structure of the stent for a bifurcated vessel fits the slant at the blood vessel bifurcation site.
