Zusammenfassung:The invention discloses a degradable intravascular stent in flexible connection. The intravascular stent comprises n segmented stents, wherein the n segmented stents are connected in series through flexible connecting pieces; the number of the flexible connecting pieces is n-1; the n segmented brackets and the n-1 flexible connecting pieces are connected in series at intervals one by one; the flexible connecting piece is a flexible film (2); the flexible film is of a stretchable structure; and the flexible film is made of a biodegradable material. The intravascular stent is formed by connecting the n segmented stents in series through the flexible film, although the deformation degree of a single segmented stent (1) is limited, the whole intravascular stent has good flexibility due to the existence of the flexible film, or the whole intravascular stent is large in deformation degree, and the deformation degree of the whole intravascular stent is large. Therefore, the device is suitable for blood vessels with
