An artificial blood vessel includes one proximal-end and at least one distal-end communicating with the proximal-end, and an inserting port positioned between the proximal-end and the distal-end. The inserting port is provided with a check valve that permits an intravascular curing device to pass through up to the proximal-end and also prevents body fluid from flowing out from the artificial blood vessel. The proximal-end is connected to the ascending aorta and the at least one distal-end is connected to one of the right brachiocephalic arterial trunk, the left common carotid artery, and the left subclavian artery.
