Zusammenfassung:A tissue removal system for extracting a tissue specimen from a patient is disclosed. The system has a retrieval bag, a first electrode, and a return electrode. The retrieval bag has a flexible container with an opening. The first electrode is coupled to an interior of the flexible container, and has a conductive wire with an exposure area, a first load-bearing area, a coating having a first active electrode surface area, and an impedance that is greater than an impedance of the conductive wire. The first active electrode surface area is less than the exposure area. The coating is configured to degrade during application of electrosurgical power and wherein the degradation expands the first active electrode surface area during the application of the electrosurgical power.
