The present invention recites a method comprising reacting in a solvent in the presence of a base. Light is launched from the light source into the input facet. The extent of light transmission through the inner conductive layer may be adjusted in accordance with the display screen’s thickness by varying the amount of carbon black particles in the coating solution. The device can also include a sheath expander that is adapted to be disposed in the central lumen of the radially expandable sheath and that is configured to flex the sidewalls to radially expand the sheath so as to fix a graft member within a bone tunnel. The running-in coating has at least two layers where a first layer is dimensionally stable and at least one additional layer has run-in capability.
