Designed for use with flexible gastrointestinal endoscopes, this device adds an independent working channel to guide instruments into the lumen, simplifying endoscopic resections such as ESD.
They support hemostasis, defect closure, tissue retrieval, stricture dilation and endoscopic access.
Selection depends on the procedure, endoscope size, working channel and device specifications.
Compatibility varies by model and should be confirmed by endoscope and working-channel dimensions.
