Abstract
The present invention involves a magnetic detachable embolization apparatus and method for embolizing an aneurysm of a blood vessel. The apparatus includes an element adapted to be detachably connected to a distal portion of a catheter for insertion within an aneurysm of a blood vessel, the element being shaped to be retained within the aneurysm, and one or more magnets carried by the element to internally induce a magnetic field from within the aneurysm to control a magnetic field controllable embolic to embolize the aneurysm. The method includes providing a magnetic-field controllable embolic within or adjacent to an aneurysm in a blood vessel, and internally inducing a magnetic field from within the aneurysm to control the magnetic-field controllable embolic to embolize the aneurysm.
