This invention is a “bowl-of-spaghetti” type intrasacular aneurysm occlusion device including: a catheter； embolic coils； a bowl or cup shaped neck bridge； an opening in the neck bridge through which the coils are inserted into the aneurysm sac； and a closure mechanism which closes the opening after the coils have been inserted into the aneurysm sac. It is a called a “bowl-of-spaghetti” type device because the neck bridge can look like a bowl and the embolic coils can look like spaghetti noodles in the bowl.
