The current invention is directed to a method of protecting UV or visible light sensitive drugs from the effects of UV or visible radiation used to form covalent bonds between a biobeneficial material and the outermost surface of an implantable medical device in order to lessen the foreign body response to the device. The tool chuck may have an input shaft mounted for rotation on the housing. This is referred to as preconnecting or prefetching the connection. The blocking mechanism can be provided as an adjustable blocking element with a an expandable and contractible mechanical blocker connected between the at least one adjustable guide and an interior wall of the tray. The methods and systems include means for detecting one or more performance problems, mapping performance problems to cubes, filling the cubes with performance data collected before, and outputting the filled cubes to an output interface usable to deploy said cubes for cube-based database performance analysis.
