Additional Caution statements in IFU: (1) Due to complaints where the loop wire at the distal end of the HF resection electrode broke after getting in contact with metal objects, such as other endoscopic equipment, implants or stents. As a result, fragments can fall inside the patient and must be retrieved. (2) The second Caution refers to the risk of sparkover when getting in contact with metal parts as this can cause uncontrolled heating of the HF-resection electrode and may result in damage and breakage to the HF-resection electrode tip
