Fem-Driven Parameter Optimization of an Electrochemotherapy Catheter Prototype

Abstract

Electrochemotherapy is an innovative minimallyinvasive technique for treating cancer, which has already been used successfully in malignancies of the skin. In order to establish this method for an interstitial use, we developed a needle-shaped probe with four expandable electrodes, which can be used as percutaneous, image-guided, minimally invasive treatment option for malignant liver tumors. For evaluating the field expansion that depends on geometry parameters, we establish a quality factor G to rate deviations in production line and to determine how precise the intervention mus be carried out. Furthermore different voltage and wiring of the electrode can be rated.
