The invention discloses an artificial
aneurysm neck and a production method thereof. The artificial
aneurysm neck comprises a tubular outer wall and a tubular inner passage arranged in the outer wall, the inner passage is of a hollow structure, and two ends of the inner passage are hermetically connected with the outer wall. The outer wall or / and the inner passage is composed of a tubular
tectorial membrane and a
metal support arranged on the surface of the tubular
tectorial membrane. The artificial
aneurysm neck is guided to a normal
aorta at the near end of a
lesion position and then released during operation, the
metal support supports the
tectorial membrane on the wall of a
normal blood vessel, and fitting between the artificial aneurysm and the
normal blood vessel is guaranteed; a tectorial membrane support is enabled to isolate aneurysm from
blood flow in a
blood vessel cavity, and a
blood flow passage of the
aorta and branched blood vessels is built; due to using of the artificial
aneurysm neck, requirements on structure of the tectorial membrane support are lowered, the artificial
aneurysm neck can be realized through a straight-tube tectorial membrane support, requirements on length of the
aneurysm neck are low, the artificial aneurysm neck is suitable for cases with extremely short aneurysm necks, production process is simplified obviously,
processing cost can be lowered, and production efficiency can be improved.
