A medical visualization system includes a combination of disposable and reusable components such as catheters, functional handles, hubs, optical devices, and the like. Other embodiments of the present invention are generally directed to features and aspects of an in-vivo visualization system including an endoscope having a working channel through which a catheter having a viewing function is passed. The catheter obtains the viewing function by being configured as a visual catheter or by having a fiberscope or other viewing device that is selectively passed through one of its channels. The catheter is preferably a steerable type that allows the distal end of the catheter to be steered from the proximal end as it is advanced through the body. Appropriate use of the in vivo visualization system includes the diagnosis and / or treatment of the duodenum, especially the biliary tree. [Selection] Figure 31 |
