The distal end of the balloon catheter is sealingly attached to the infusion catheter. And the balloon catheter has at least one communicating channel disposed from the outer wall to the inner wall of the balloon catheter. A suction catheter is disposed between the balloon catheter and the infusion catheter. The suction catheter is in fluid communication with the at least one communicating channel in the balloon catheter.
