Abstract
A technique facilitates actuation of a variety of tools in many types of environments. The actuation technique employs a closed conduit, such as a closed tube, arranged in a curvilinear structure. By applying a differential pressure to the closed conduit, the curvature of the curvilinear structure is changed. This change can be used to actuate a corresponding tool between desired operational positions.
