A system for flushing a vascular site, the system comprising: (I) a first two lumen catheter comprising: (A) a proximal end; (B) a distal end; and (C) a three port manifold located at the proximal end, the three port manifold comprising at least two offset ports having luer valves and a central port comprising a Touhy-Borst valve, and the proximal and distal ends being separated by a non-coaxial two lumen tube; and (II) a second multilumen catheter inserted inside of one of the two lumens of the first two lumen catheter, the second multilumen catheter being a three lumen catheter comprising: (i) a proximal end; (ii) a distal end; and (iii) a three port manifold located at the proximal end, each port of the three port manifold comprising a luer valve, the proximal and distal ends being separated by a non-coaxial three lumen tube. The system is useful for simultaneously flushing a vascular target site with two different fluids - for example, for flushing a calcified vascular lesion with an acidic dissolution fluid and a pH elevating buffer solution.
