A vascular stent, a conveying balloon thereof, and an implanting system. The vascular stent comprises a flexible light-transmitting body (1). The flexible light-transmitting body (1) is provided with a hardenable channel (2). The hardenable channel (2) is arranged in the circumferential direction and the axial direction of the flexible light-transmitting body (1). The hardenable channel (2) is used for filling a liquid photocuring supporting material (3), and the liquid photocuring supporting material (3) is cured after being illuminated so as to radially support the flexible light-transmitting body (1). In the present invention, by means of the characteristic that the liquid photocuring material is hardened into a fixed material after being illuminated, the flexible light-transmitting body is radially supported； by means of the hardenable channel extending in the circumferential direction and the axial direction, it can be ensured that the implanted vascular stent has a good radial supporting capability； and the vascular stent provided in the present invention has a simple structure, is convenient to implant and has lower cost compared with a metal stent.La présente invention concerne un tuteur vasculaire, un ballonnet de transport associé, et un système d'implantation. Le tuteur vasculaire comprend un corps flexible (1) transmettant la lumière. Le corps flexible (1) transmettant la lumière comprend un canal durcissable (2). Le canal durcissable (2) est disposé dans la direction circonférentielle et dans la direction axiale du corps flexible (1) transmettant la lumière. Le canal durcissable (2) est utilisé pour charger un matériau (3) liquide de support photodurcissable, et le matériau (3) liquide de support photodurcissable (3) est durci après son exposition à la lumière de manière à supporter radialement le corps flexible (1) transmettant la lumière. Dans la présente invention, au moyen de la caractéristique selon laquelle le matériau liquide photodurcissable est
