A medical electrode device comprises a flexible bag-like member which is formed on the side in direct contact with a living body and to and from which is charged and discharged a cooling medium, and a flexible electrode secured to the bag-like member, wherein an inner surface of the flexible bag-like member is at least partially joined to the other opposing inner surface of the bag-like member to each other so as to form a partitioned flow channel for the cooling medium in the inside of the bag-like member. The medical electrode device, when applied to the surface of a living body with a small radius of curvature, can be in an intimate contact with the living body without disturbing the distribution of the electric field, can attain a satisfactory cooling effect due to the use of a direct cooling system and the uniform flow distribution of water through the partitioned flow channel, and can perform efficient warming of the targeted lesion in the living body. |
