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. A polymeric articulation joint at the distal end of the endoscope allows the distal end to be oriented by 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.

An imaging endoscope assembly comprising: an elongate shaft comprising: a proximal portion having a first stiffness,a cylindrical distal portion having a second stiffness, the second stiffness being different than the first stiffness, the distal portion terminating at a distal end ring;a steering
