An apparatus for processing at least one optical waveguide comprises a combination of a stripper, a cleaner and a cleaver. In the method of inspecting the display panel, a first image is captured from the display panel in a state in which no pattern is applied to the display panel. The product then is fused whereby the mechanical embossing in surface areas which are not disposed over the printing ink relaxes and becomes smooth. When the sealing device is withdrawn such that the sealing device is deployed such that it blocks the blood flow into the distal port, the user will know the location of the sealing device.
