An aneurysm embolization device includes at least: a sac-shaped balloon dome part which is inserted into the aneurysm, then expanded and left therein; and a balloon plane part which is provided at an opening of the balloon dome part and covers a mouth part of the aneurysm. The balloon plane part has a hole communicating with the inside of the balloon dome part. The aneurysm embolization device thus constituted is housed into a lumen of a protective outer sheath member formed of a flexible elongated-body having the lumen therein. A tip part of the protective outer sheath member is placed at a desired position, and the aneurysm embolization device is ejected from the tip part of the protective outer sheath member. The aneurysm embolization device thus ejected includes the balloon dome part placed at a desired position and the balloon plane part deploying to cover the desired position. |
