The invention relates to a drug eluting stent in a living body, which comprises a frame, a plurality of elastic limbs, a plurality of elastic; a balloon connected between the elastic limbs; and a drug eluting portion embedded outside the frame. The in vivo drug eluting stent provided by the invention can inhibit smooth muscle cell proliferation and reduce restenosis in the stent; the endothelial progenitor cells in the blood flow are captured, and the endothelial progenitor cells at the damaged part are gathered again after the device is implanted, so that the endothelial healing is promoted, the thrombus in the stent is reduced, and the function of promoting the endothelial repair is also realized. |
