A catheter for removing an object in a body lumen includes an outer tube, a shaft surrounded by the tube, a cutting member connected to the shaft to be rotated with respect to a rotation axis, a guide wire tube attached to the outer tube and having a first lumen for a guide wire and second lumens, a metal member attached to the wire tube, a part of the metal member surrounded by the member, a distal tip attached to the wire tube and having a third lumen communicating with the first lumen, and a pusher extending along the shaft, connectable to the distal tip or the metal member, and including wires that can pass through the second lumens. The pusher causes the cutting member to move toward a first surface of the body lumen when contacting an opposite second surface of the body lumen.
