Patent ID: 8764724

Claim:
A method of sucking foreign matter from a blood vessel, comprising: inserting into a blood vessel a guiding catheter until a distal side of the guiding catheter reaches a proximal side of a target location; simultaneously moving a suction catheter and a protective catheter within a lumen of the guiding catheter, the suction catheter comprising a tubular portion and a solid wire portion extending from a proximal side of the tubular portion, towards a position in which a distal side of the tubular portion projects forwardly beyond the distal side of the guiding catheter, and a proximal side of the tubular portion is disposed inside of the guiding catheter; withdrawing the protective catheter from the suction catheter; rotating the suction catheter until a distal end of the suction catheter is introduced to a location in front of a thrombus; and applying suction to the guiding catheter which is transmitted to the tubular portion for sucking the foreign matter into the distal side of the tubular portion.
