Abstract
A branch vessel stent comprising a stent body and a first developing member, wherein the first developing member comprises a first developing portion and a second developing portion. A length of the first developing portion and a length of the second developing portion in an axial direction of the stent body are both not less than 0.5 mm. A distance between the intersections of the first developing portion and the second developing portion on a plane perpendicular to the axial direction of the stent body gradually increases from a position where the distance is the minimum distance to an end that is away from a first end of the first developing portion or the second developing portion. The minimum distance between the intersections of the first developing portion and the second developing portion on a plane perpendicular to the axial direction of the stent body is not more than 2 mm. The branch vessel stent is capable of accurately positioning the position thereof, and is capable of identifying a distortion and knotting of the stent for the branch vessel.
