Abstract
The present invention involves a magnetic embolization apparatus for embolizing an aneurysm of a blood vessel. The apparatus includes a coiled element adapted for insertion within an aneurysm of a blood vessel, the coiled element shaped to be retained within the aneurysm, and one or more permanent magnetic segments carried by the coiled element to internally induce a magnetic field from within the aneurysm to control a magnetic field controllable embolic to embolize the aneurysm.
