PURPOSE: A complex stent for expanding the lumen is provided to simplify its manufacturing procedure and to achieve a mass production, and to accurately adjust an expansion force of the stent according to the disturbance of the body. CONSTITUTION: The complex stent(2) for expanding the lumen comprises a first filament(4) forming a mesh structure constructed by a plurality of units reciprocally arranged in a zigzag pattern from a reference point on the end of a reference circumference to the other end thereof; and a second filament(6) forming the mesh structure constructed by a plurality of units reciprocally arranged in a zigzag pattern from a certain position different from the reference point of the first filament to the other end thereof.
