The present invention is an optic used for producing a desired beam pattern having a body portion having a height and a thickness, and at least one sidewall profile, as well as an input port for receiving light from a light source. At least one sealed window is provided in the vessel, the at least one sealed window being optically coupled to at least one end of the length of hollow core photonic crystal fiber. In some examples, the plurality of cathodic wires may have at least two arrays of cathodic wires, each array contains at least one row of cathodic wires, and each row extends along the catholyte pathway. The first user may then provide user input identifying a desired action to take with respect to one or more of the second users. After the radiolucent instrument driver is in the desired orientation, the control device sends a driver control signal to the radiolucent instrument driver that causes the radiolucent driver to insert a medical instrument or device through the predetermined point to a location proximate a target point in a patient.
