An artery, vein, aneurysm, vascular malformation, or arterial fistula can be occluded by endovascular electrothrombosis by endovascular insertion of one end of platinum guidewire (30) into the vascular cavity, followed application of a positive current charge. The end of the guide wire (30) is then separated from said wire by the electrolytic separation of the end and the guide wire (10). A part (26) of the wire (10), connected between the end (30) and the body of the guide wire (10) is made of stainless steel and exposed to blood flow so that, under continuous application d 'a positive current to the exposed part, it is corroded in at least one place, and the end (30) is then separated from the body of the guide wire (10). The guidewire (10) and the micro-catheter are then removed, leaving the end of the wire (30) implanted in the thrombus formed inside the vascular cavity. |
