The present invention relates to a medical double balloon catheter electrode device, which comprises a tube which is a flexible member extended in the longitudinal direction to be inserted into a body; a first expansion part formed on the front end of the tube; a second expansion part located outside the first expansion part for the first expansion part to be located inside; a first air supply line supplying at least one among a gas or a liquid to the first expansion part; and a second air supply line supplying at least one among a gas or a liquid to the second expansion part. According to the present invention, the first expansion part among the double structure expansion parts is linearly expanded, when inserting a catheter into an epidural space to easily reach a part clogged by foreign substances, while expanding an intervertebral foramen by expanding the second expansion part not only to be inserted well by penetrating a narrow part, but also to have an effect of use another one as a reserve even one is damaged. |
