Abstract: A disposable endoscope body having an enclosure in its distal end for a non-disposable element, such as a video camera head. Because of its complexity and sensitivity, the camera head is non-disposable and cannot be sterilized.

A dispensing kit is described, for supplying the sterile endoscope body and for installing and sealing the camera with a minimum of manual intervention.
