Abstract
Provided are a guide wire and a catheter system. The catheter system includes a hollow catheter inserted into a fistula of a living body, the catheter having two open ends and a coaxially-formed lumen; and a bipolar electrode type guide wire including a wire body formed of a metal and elongated to be inserted into the catheter in one direction, an insulating material coated on an outer periphery of the wire body to insulate the wire, a first electrode attached to one end of the wire body, a second electrode spaced a predetermined distance apart from the first electrode, a first lead elongated along the wire body to be attached to the first electrode to electrically connect a radio-frequency generator for generating radio-frequency current to the first electrode, and a second lead elongated along the wire body to be attached to the second electrode to electrically connect the radio-frequency generator to the second electrode, the second lead being electrically insulated from the first lead.
