Provided is a catheter (100) including: a flexible sheath (1); a flexible shaft (2) which is provided by being inserted inside the sheath (1) and which is capable of sliding in a longitudinal direction of the sheath (1); an electrode section (10) which is capable of being in contact with a renal artery wall. The catheter (100) is configured such that a plurality of electrodes (12) provided to the electrode section (10) do not exist on a single plane perpendicular to a moving axis of the shaft (2). According to the present invention, it is possible to easily and quickly perform renal artery ablation while avoiding post-ablation renal artery stenosis. |
