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.
A sterile electrosurgical device which consists of a handpiece with mechanical and/or electrical controls, and a monopolar electrode, intended to deliver electrosurgical 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 may include a lumen for suction/irrigation; it requires a patient contact return electrode to complete the circuit. It is available in a variety of forms (e.g., forceps or snare with ring handles, rigid probe with controls) and may be designed to also mechanically cut tissues. This is a single-use device.
