1. An apparatus for flushing a lumen of a catheter instrument, comprising:

  • an interface valve having a proximal end and a distal end that is adapted for attachment to a proximal end of the catheter instrument, the proximal end and lumen of the interface valve being configured to receive a working instrument for insertion into the lumen of the catheter instrument;

    a fluid supply line coupled to the interface valve and being in fluid communication with at least a portion of the interface valve lumen;

    a first purge line coupled to the interface valve; and

    a second purge coupled to the interface valve, wherein the first and second purge lines are controllable such that fluid flowing into the interface valve lumen can be manipulated to flow in different directions through different portions of the interface valve lumen for evacuation through different purge lines.
