Ablation instrument and manufacturing method thereof

Abstract

An interior cooled ablation instrument includes a curved section adjoining its distal end in which the ablation instrument is bent relative to its axial direction. The amount of the angle is preferably defined to one-third up to two-thirds, and preferably half of the maximum angulation. The maximum angulation can significantly exceed an absolute value of 140°. Due to the pre-bend in the curved section, a kinking of the hose of the ablation instrument and thus an impairment of the electrode cooling as well as the occurrence of high dam pressure can be effectively avoided. In doing so, the ablation instrument allows a freer work, even more considerably oriented at medical aspects and considerations compared to completely stretched ablation instruments.
