<P>PROBLEM TO BE SOLVED: To provide an intravascular stiffener easily inserted into a narrow blood vessel and easily recovered from the blood vessel. <P>SOLUTION: An embolization catheter 6A is passed into a blood vessel 4, an embolization coil 7 made of platinum is pushed out from the embolization catheter 6A indwelled in aneurysm 5, a protect coil is pushed out from a microcatheter 6 is pushed out, and a coil part 2 is placed in the blood vessel 4 of the aneurysm 5 with a large neck to separate the blood vessel 4 from the aneurysm 5. At this time, the embolization catheter 6A is positioned outside the coil part 2. A wire constituting the coil part 2 is so densely coiled as to come into contact with each other. The inside of the aneurysm 5 is tightly embolized by the embolization coil 7, and the embolization catheter 6A is removed by separating the embolization coil in the embolization catheter 6A from the embolization coil in the aneurysm 5. <P>COPYRIGHT: (C)2008,JPO&INPIT |
