Abstract
An articulating mechanism for use in a medical device, such as an endoscope or a catheter, includes a series of stacked links disposed adjacent to one another and movable with respect to each other. Each link includes a front face tapered to a pair of pivot points and a rear face defining a wedge shaped recess for receiving the pivot points of the adjacent link. Pull-wires provide tension and hold the staked links together while also allowing for controlled bending of the distal portion by movement of one or more of the pull-wires.
