• an endoscope including a tubular visualization device;
• and
• a tubular sheath having a diameter of 3 mm or less, the sheath having a distal optical assembly to image a field of view, the sheath further comprising an annular array of optical fibers,
• wherein an angle of view of the visualization device is offset from an insertion axis of the endoscope device.

A method for arthroscopic surgery comprising:

• inserting a distal end of an endoscope system through a first cannula channel into a body cavity, the endoscopic system including a tubular endoscopic device and a tubular sheath having a diameter of 3 mm or less;
• inserting a surgical tool through a second cannula channel;
• and
