ABSTRACT:
According to the present invention, a sheath has flexibility, and includes a first lumen for guiding a conducting wire in the sheath and a second lumen for injecting contrast medium, which are made of insulating material. The wire exposes itself outside at openings formed in the terminal position of the first lumen, and thus forms a dissecting section for dissecting a contact tissue with supplied high-frequency current. The proximal portion of the sheath is connected to a bifurcating section for bifurcating the sheath into a first path having substantially the same cross-sectional area as the first lumen and communicating with the first lumen for guiding the wire so that the wire will not buckle up and a second path communicating with the second lumen. An operation handle for advancing or withdrawing the wire is connected externally to the back of the first path.
