Fem-Driven Parameter Optimization of an Electrochemotherapy Catheter Prototype

Electrochemotherapy is an innovative minimally- invasive technique for treating cancer, which has already been used successfully in malignancies of the skin. In or- der to establish this method for an interstitial use, we de- veloped a needle-shaped probe with four expandable elec- trodes, which can be used as percutaneous, image-guided, minimally invasive treatment option for malignant liver tu- mors. For evaluating the field expansion that depends on geome- try parameters, we establish a quality factor G to rate de- viations 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.
