ABSTRACT:
An endoscope, particularly for use as a uretero-renoscope, includes a catheter head piece with a flexible catheter body in the form of a semi-flexible hose having a highly flexible tip, the hose being divided into internal axially extending conduits by interior walls which bisect the interior of the catheter body in a asymmetric fashion so that the conduits are not of equal size. The head piece is in the form of an ergonimcally shaped rod-like handle which surrounds an eye piece and is disclosed coaxial with the catheter body.
