The application provides a micro catheter, comprising a tube body, the tube body comprising an inner layer, an intermediate layer and an outer layer, the intermediate layer comprising a reinforcing area, a body area and a weakening area arranged in sequence along the circumferential direction of the tube body, the bending stiffness of the reinforcing area, the body area and the weakening area decreasing in sequence. Therefore, the bending stiffness of the tube body on the side of the reinforcing area is stronger, so that the micro catheter has better pushing performance and supportability on the side of the reinforcing area, and the kinking caused by the transitional bending of the micro catheter can be avoided. Meanwhile, the bending stiffness of the tube body on the side of the weakening area is smaller, the local flexibility is higher, and the bending performance is better. The body area maintains the basic stiffness and performance of the tube body and forms a smooth transition between the reinforcing area and the weakening area, so that the local stress concentration does not cause the bending failure of the catheter, thereby realizing the passability of the micro catheter in special tortuous blood vessels and the plasticity of the head end.
