Zusammenfassung:	The utility model discloses a medicine balloon which comprises a balloon body and a medicine coating located on the surface of the balloon body, and the medicine coating comprises medicine and excipient. The drug coating comprises a near-end coating, a middle-section coating and a far-end coating, the drug loading density of one of the near-end coating and the far-end coating is larger than that of the middle-section coating, and the drug loading density of the other one of the near-end coating and the far-end coating is not smaller than that of the middle-section coating. The stent restenosislesion is treated; the medicine balloon is selected for pressurizing according to lesion characteristics; the drug balloon plays a supporting role, and the coating part with high drug loading densityis attached to the serious stenosis lesion at the near end or the far end, so that the drug content is selectively improved, the stenosis rate of a serious lesion area is reduced, the total drug content of the whole lesion is
