Main function of the new RF-assisted device for rapid bloodless resection. Top: Lateral view of the probe showing the distal section (D) with the blade, the proximal section (P) joined to the insulated part of the probe (green), and the advance direction of the probe on the target tissue. Bottom: Cross-sectional views of a fragment of target tissue showing two sequential applications. Each application consists of two steps: first, the tissue is heated (and coagulated) by applying radiofrequency currents (arrows) using the proximal section (steps 1 and 4), after which the blade of the distal section resects the previously coagulated tissue (steps 2 and 5) [18].
