Abstract
An apparatus where a side-view duodenoscope 2 is provided, a probe catheter is slidable through the side-view duodenoscope 2 and a guide wire is provided for arrangement in the side-view duodenoscope 2 and the probe catheter. The objective is to ensure reliable, systematic and reproducible representation of the gall bladder lumen by endoscopic-retrograde means. This is achieved in that a guide catheter is slidable over the guide wire while a probe wire 12 is slidable through the guide catheter into the gall bladder luman 20. The probe wire 12 permits a small endoscope or an irrigation catheter to be passed into the gall bladder lumen.
