Probe (14) for high-frequency thermal ablation with an insulating tube (18), at the distal end of a metal electrode (16) is provided, the spatial extent of a cylindrical shape is changed to a star-shaped shape, wherein the metal electrode (16) by a plurality flexible arms (26) are formed, the distal and proximal ends of which are connected to each other, wherein the distal and / or proximal ends of the arms (26) are electrically connected to a connector for supplying a high frequency current, wherein the flexible arms (26) themselves form the electrode and the shape of an arm (26) approximately in the middle (M) deviates from its shape at both ends, so that it has a bending stiffness, which favors the star-shaped formation of the metal electrode (16), wherein the outer contour of an arm ( 26) approximately in the middle (M) is approximately spiral, zigzag, wavy or meander-shaped and rectilinear at its two ends. |
