A Tubular Electrode for Radiofrequency Ablation Therapy
In the last two decades radiofrequency ablation (RFA)
has been considered a promising medical procedure for the treatment
of primary and secondary malignancies. However, the needle-based
electrodes so far developed for this kind of treatment are not suitable
for the thermal ablation of tumors located in hollow organs like
esophagus, colon or bile duct. In this work a tubular electrode
solution is presented. Numerical and experimental analyses were
performed to characterize the volume of the lesion induced. Results
show that this kind of electrode is a feasible solution and numerical
simulation might provide a tool for planning RFA procedure with
some accuracy.
