A remotely bi-directional deflectable electrophysiologyablation catheter of the type intended for placing into an interior passage of the heart is disclosed. The magnetic chip interacts with an identifying unit, to determine the compatibility of the toner cartridge. A large number of frequency-correlated depth channels are used to acquire multiple depth scans of a sample. The entire assembly can be quickly removed from the motorcycle and stored, if desired. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
