A tissue removal system for extracting a tissue sample from a patient is disclosed. The system has a draw bag, a first electrode, and a return electrode. The take-out bag has a flexible container having an opening. A first electrode is coupled to the interior of the flexible container and has an impedance greater than the impedance of the conductive line having an exposed region, the first load-holding region, the coating having the first active electrode surface region, and the conductive line. The first active electrode surface area is smaller than the exposed area. The coating is configured to degrade during application of electrosurgical power, wherein the degradation enlarges the first active electrode surface area during application of electrosurgical power. |
