An endoscope with a flexible inserted portion intended for the visual examination and treatment of the small intestine (duodenum, jejunum, and ileum). It is inserted into the body through the mouth or the anus during enteroscopy typically to examine strictures, assess Crohn's's disease, or take biopsies. It may be designed to be manually inserted or may be designed with features to assist/power insertion (e.g., push/pull double-balloons, powered spiralling motor). Anatomical images are transmitted to the user by a video system with an image sensor chip at the distal end of the endoscope and the images showing on a monitor. This is a reusable device.
