Abstract

An endoscope includes a substantially rigid shaft having a distal end and a proximal portion, the shaft having a first lumen and a second lumen separate from the first lumen, the second lumen containing one or more objective lenses disposed at the distal end thereof. A housing is mounted on the proximal portion of the shaft, the housing including an eyepiece mount and a light input port. An image fiber bundle is disposed in the second lumen, the image fiber bundle extending proximally from adjacent the one or more objective lenses to the eyepiece mount. An illumination fiber bundle is disposed in the second lumen, the illumination fiber bundle extending proximally from the distal end of the shaft to the light input port.
