A flexible device intended to be inserted through an endoscope to ligate, cauterize, and cut polyps, or other mucosal lesions in the gastrointestinal (GI) tract, using high frequency current during endotherapy. It consists of a flexible insulated insertion sheath, a snare loop attached to the distal end of the sheath, and an operating wire connected to both the loop and a handle which controls the operating wire. The proximal end of the operating wire is connected to a high frequency power supply unit. This is a single use device.
An electrosurgical device consisting of a handpiece with mechanical and/or electrical controls, and a monopolar electrode, intended to deliver a current from a system generator directly to tissues for cutting/coagulation/ablation during endoscopic (including laparoscopic, arthroscopic) surgery. It includes a long thin electrode connected to the handpiece and requires a patient contact return electrode; it may include a suction/irrigation lumen and may feature a magnetic guidance sensor for electromagnetic tracking. It is available in a variety of forms (e.g., forceps or snare with ring handles, rigid probe) and may also be designed to mechanically cut tissues. This is a single-use device.
