A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. One exemplary system embodiment includes logic for recording instruction and state data associated with events countable by performance monitoring logic associated with a pipelined processor. According to an embodiment, for example, the number of pixels of a two-dimensional sensor required for fluorescence analysis of the regions with the biologically-related molecules immobilized can be set to several hundred times to fifty times smaller than that in the conventional case without degrading the measurement accuracy. This pressure forces the locking mechanism to disengage from the action mechanism.
