An artificial aneurysmal neck and manufacturing method thereof the artificial aneurysmal neck comprises a tubular outer wall (3) and a tubular built-in channel (5) the built-in channel (5) is disposed in the outer wall (3), and has a hollow structure two ends of the built-in channel (5) are hermetically connected to the outer wall (3) the outer wall (3) and/or the built-in channel (5) comprise a tubular coating and/or a metal support (31) the metal support (31) is disposed on the surface of the tubular coating. The artificial aneurysmal neck is released in an operation after being introduced to a normal aorta at the near-end of a lesion site the metal support (31) supports the coating material on the normal blood vessel wall to ensure a good fit between the artificial aneurysmal neck and the normal blood vessel, and enable the coating support to isolate the aneurysm from the bloodstream in a blood vessel cavity so as to establish a bloodstream channel between the aorta and branch blood vessels in addition, the use of the artificial aneurysmal neck reduces the structural requirement on the coating support, can be realized as a straight-pipe coating support, has a low requirement on the length of the aneurysmal neck, and is suitable for cases of extremely short aneurysmal necks, thus clearly simplifying the production process, reducing manufacturing costs, and improving production efficiency.Linvention concerne un collet anévrismal artificiel et son procédé de fabrication. Ledit collet anévrismal artificiel comprend une paroi extérieure tubulaire (3) et un canal tubulaire intégré (5). Le canal intégré (5) est disposé dans la paroi extérieure (3) et est de structure creuse. Deux extrémités du canal intégré (5) sont hermétiquement reliées à la paroi extérieure (3). La paroi extérieure (3) et/ou le canal intégré (5) comprennent un revêtement tubulaire et/ou un support métallique (31), le support métallique (31) étant disposé sur la surface du revêtement tubulaire.
