The stent of the present invention combines a helical strut band interconnected by coil elements. In accordance with the present invention, it has been determined that the application of microcurrent signals at particular frequencies to the eye for particular periods of time stabilizes and even improves conditions of macular degeneration and other ocular diseases. A flow manager may generate a unified rule set according to the received packet flow rules and may additionally validate the unified rule set to identity errors. The control system may operate in conjunction with a motion detection system that includes at least one motion detection sensor for detecting motion.
