An endoscopic imaging system includes a reusable control cabinet having a
number of actuators that control the orientation of a lightweight
endoscope that is connectable thereto. The endoscope is used with a
single patient and is then disposed. The endoscope includes an
illumination mechanism, an image sensor, and an elongate shaft having one
or more lumens located therein. An articulation joint at the distal end
of the endoscope allows the distal end to be oriented by the actuators in
the control cabinet. The endoscope is coated with a hydrophilic coating
that reduces its coefficient of friction and because it is lightweight,
requires less force to advance it to a desired location within a patient.
