An artificial blood vessel which includes one proximal-end (14) and at least one distal-end (16a) communicating with the proximal-end (14) and an inserting port (22) positioned between the proximal-end (14) and the distal-end (16a), the inserting port (22) being provided with a check valve (28) that permits an intravascular curing device (36) to pass through up to the proximal-end (14) and also prevents body fluid from flowing out from the artificial blood vessel. The proximal-end (14) is connected to the ascending aorta (12c) and the distal-end (16a, 16b, and 16c) are connected respectively to the right branchiocephalic arterial trunk (24a), the left common carotid artery (24b), and the left subclavian artery (24c).
