Figure 4. (A) Schematic layout showing multiple punctures made on the same septum using each wire under different dilator-wire tip distances and EG power settings, respectively: (B) 1mm and 35W, (C) 3mm and 20W, (D) 3 mm and 35W, (E) 3mm and 50W, and (F) 5mm and 35W. The dedicated wire in all experiments delivered a preset power of 5W. (Scale bar is 1mm.)
