Illustration of electrode deflection in a mechanical stress region due to needle insertion. (a) The electrode insertion in stiff tissues may cause (b) an inward deflection or (c) an outward deflection. Two possible directions of needle deflection are shown. Illustrations were created in Microsoft VISIO Professional 2019 v.2111 (Microsoft Corporation, Washington, USA; https://www.microsoft.com/en-us/microsoft-365/visio/flowchart-software) (d,e) are two cases of electrode deflection returned to electrode manufacture. (f) Numerical simulation geometry showing the ESOPE Type II electrode inserted into the tissue with standard configuration. The geometry was generated by COMSOL Multiphysics v.5.1 (COMSOL Inc., Stockholm, Sweden; https://www.comsol.com/comsol-multiphysics). The highlight depicts the directions for the anode needles deflection studied in this work.
