Regarding artificial blood vessels used for the treatment of aortic aneurysms, medical device manufacturers in Tokyo have begun voluntary recovery because they may cause rupture of the aortic aneurysms in the worst case, such as damage in the body.

Since no health hazards have been reported so far, Medtronic Japan said, "We apologize for the inconvenience. We will proceed with the collection as soon as possible and provide information to medical institutions so that we can take appropriate measures. I want to. "
