The invention relates to an in-mold labeling method, and to molded plastic articles having an in-mold label as described herein. The operator places a mapping catheter at a desired location, and commands the catheter guidance system by either selecting a point on that catheter or one of the catheter electrode electrocardiograms. The travel backpack is arranged in a first configuration and a second configuration. All controllers are connected to a V+ line and a COMMON line and a RETURN line. The polysilicon segments are situated in a core region of the substrate.
