An invasive, distal component of an electrosurgical assembly intended to deliver electrosurgical current in a monopolar configuration (i.e., used with a patient contact return electrode) to tissues for cutting/coagulation/ablation during endoscopic (e.g., laparoscopic, arthroscopic) surgery. It available in a variety of forms (e.g., exchangeable electrode for electrosurgical forceps, rigid electrode, flexible endoscopic probe) which may include a lumen for suction/irrigation. It does not include a handpiece/housing and has no electrical or mechanical controls (e.g., does not include controlling ring-handles); it is not intended for gas-enhanced electrosurgery. This is a reusable device.
