Title:
APPARATUS AND METHOD FOR CONTROLLING A MAGNETICALLY CONTROLLABLE EMBOLIC IN THE EMBOLIZATION OF AN ANEURYSM
Document Type and Number:
WIPO Patent Application WO2002053041
Kind Code:
A9
Abstract:
The present invention involves a magnetic embolization apparatus and method for embolizing an aneurysm of a blood vessel. The magnetic embolization apparatus includes a catheter having a distal portion adapted for insertion within an aneurysm of a blood vessel, a permanent magnet carried by the distal portion of the catheter to internally induce a magnetic field from within the aneurysm to control a magnetic field controllable embolic to embolize the aneurysm, and an electromagnet carried by the distal portion of the catheter to internally induce a magnetic field to control delivery of the magnetic field controllable embolic. The method includes delivering a magnetic-field controllable embolic into an aneurysm, inducing a magnetic field in the aneurysm to control the magnetic-field controllable embolic to embolize the aneurysm with the permanent magnet of the catheter, and controlling the delivery of the magnetic-field controllable embolic into the aneurysm with an electromagnet.
