An intravascular foreign matter suction assembly is insertable into a blood vessel having a relatively small diameter and exhibits a high suction force. The intravascular foreign matter suction assembly includes a combination of a guiding catheter (1) for being inserted to an ostium of a coronary artery of the aorta and a suction catheter (2,9) inserted in the lumen of the guiding catheter (1) and extending farther than the distal end of the guiding catheter (1) for removing a foreign matter in a blood vessel which exists at a target location in the coronary artery. The suction catheter (2,9) includes a tubular portion (24,91) provided on the distal end side and a wire portion (25) provided on the proximal end side of the tubular portion (24,91) and wherein the wire portion (25) has a distal end embedded in a wall which forms the tubular portion (24,91).
