PROBLEM TO BE SOLVED: To provide a medical visualization system including a combination of disposable and reusable components such as a catheter, a functional handle, a hub, an optical device.SOLUTION: The other embodiments of the present invention generally aim at the features and aspects of an in-vivo visualization system including an endoscope having operation channels allowing the catheter having a viewing function to pass therethrough. The catheter obtains the viewing function by constituting the catheter as a visual catheter, or by having a fiberscope or another viewing device to be allowed to pass through one of the channels selectively. The catheter is preferably a steerable type to be steered from its proximal end when advancing the distal end of the catheter in a body. The in-vivo visualization system is properly used also for diagnosing and/or, for example, treating the duodenum, in particular, the biliary tree. |
