Presentation of a numerical simulation analysis of a modified stent-based electrode to be used in the radio frequency ablation of tumours located in hollow organs. The objective is to achieve a more regular volume of induced lesion without imperilling the ductal organ where the tumour is located. Three types of bipolar electrode configurations were considered, formed by 2, 3 and 5 tubular segments. Numerical simulations were performed considering a tumour located in the bile duct, where two important blood vessels – the portal vein and the hepatic artery – have a significant impact due to the convective heat transfer caused by the blood flow (heat sink effect). The results obtained show that the 5-segment electrode arrangement allows a regular volume for the induced lesion, independently of the different values of applied voltage considered Presentation at the EHE2014 - 5th International Conference on Electromagnetic Fields, Health and Environment. ]]>
