ABSTRACT:
An endoscope has a first segment with a proximal end and a distal end and is symmetric about an axis. A second segment, comprising a flexible and interconnected linkage system, is pivotably coupled to the first segment and, when subject to an applied force, is configurable along an arc having a variable radius of curvature. The linkage system is capable of articulation through an angle from zero degrees through about 280 degrees.
