Bipolar electrode type guide wire and Catheter system using the same

摘要

The present invention relates to a medical guide wire and the catheter system using them. Guide wires of the bipolar electrode system according to the present invention is formed of an electrically conductive material as long, inserted in the hollow of the catheter which is inserted into a tubular organ of a living body has end portions made of a first wire and the electrically conductive material is arranged to protrude from the catheter , and the main line portion is formed long and arranged to be spaced apart from the first wire, is formed into a spiral extending from the main line portion and a second wire having a coil part which is inserted inside the first wire, the first wire and a second except only the front end portion of each wire is electrically isolated between the first wire and the second wire, the tip end portion and the distal end of the second wire of the first wire is characterized in that is disposed a predetermined distance apart.
