A balloon catheter assembly for delivering nano-carriers to bifurcation lesions in one or more of a main branch and a side branch of a blood vessel bifurcation within 30 to 90 seconds is provided. User-selectable preferences may be selected such as a longer or shorter list of candidates; a longer or shorter representation keyword candidates; a full syntax or partial syntax representation of a candidate; and a character case representation of a candidate. Each of a plurality of block magnets has substantially the same width and is positioned within one of the magnet portions of the cavities. Latency due to the idle clock cycles is minimized by selectively modifying the sequence of layers through the decoding process and the sequence of messages processed by a certain layer.
