In-vivo visualization system

摘要

Several embodiments of the present invention are generally directed to medicalvisualization systems that comprise combinations of disposable and resuablecomponents, such as catheter, functional handles, hubs, optical devices, etc.Other embodiments of the present invention are generally directed to featuresand aspects of an in-vivo visualization system that comprises an endoscope havinga working channel through which a catheter having viewing capabilities is routed.The catheter may obtain viewing capabilities by being constructed as a visioncatheter or by having a fiberscope or other viewing device selectively routedthrough one of its channels. The catheter is preferably of the steerable typeso that the distal end of the catheter may be steered from its proximal end as itis advanced with the body. A suitable user for the in-vivo visualization systemincludes but is not limited to diagnosis and/or treatment of the duodenum, andparticularly the biliary tree.
