Abstract
A magnetic embolization apparatus for embolizing an aneurysm of a blood vessel includes a catheter with a distal portion, and a permanent magnet and an electromagnet carried by the distal portion to internally induce a magnetic field in the aneurysm to control a magnetic field controllable embolic to embolize the aneurysm. A related method of embolizing an aneurysm of a blood vessel includes delivering a magnetic-field controllable embolic into an aneurysm, and simultaneously inducing a magnetic field in the aneurysm with a permanent magnet and an electromagnet to embolize the aneurysm.
