Claim Text:
1. An endoscope comprising: a shaft tube; a fibre tube disposed in a longitudinal direction within the shaft tube; an image guide having a distal objective, the image guide being disposed within the fibre tube; and an optical fibre bundle disposed in a cross-sectional area between the fibre tube and the shaft tube; wherein the fibre tube has a lumen having an elongate cross-section in a plane perpendicular to the longitudinal direction; the elongate cross-section is constant over a length of the shaft tube; and the distal objective comprises first and second distal objectives corresponding to first and second viewing directions, one of the first and second distal objectives extending in a first direction from the other of the first and second distal objectives, the fibre tube being oriented such that a larger dimension of the elongate cross-section corresponds with the first direction to accommodate cross-sectional areas of the first and second distal objectives within the elongate cross-section of the fibre tube.
