1. A method for providing maintenance treatment to a catheter utilizing a syringe device having:

  • a support structure having at least two separate compartments for containing respective liquids;

    a distal wall traversing the support structure proximate a distal end thereof;

    a duct extending through the distal wall enabling liquid to exit the at least two compartments;

    at least one plunger movably affixed to the support structure proximate the proximal end thereof for infusing liquids from the device through the duct upon activation of the at least one plunger, anda closure plug removably attached to the support structure at a distal end thereof,the support structure, the at least two compartments and the at least one plunger being adapted to infuse the respective liquids sequentially in a preselected order into the catheter lumen;

    the method comprising the steps of;

    connecting to the distal end of the syringe device, with the closure plug already attached to the support structure, to a proximal end of a catheter such that the closure plug is connected to the catheter proximal end and the duct is in fluid communication with a lumen of the catheter,activating the at least one plunger to express a first liquid from a first compartment, through the duct and into the lumen;

    activating one of said at least one plunger or another plunger associated with the second compartment, to express a second liquid from a second compartment through the duct and into the lumen; and

    removing the syringe device from the catheter proximal end such that the closure plug is detached from the support structure while remaining connected to the catheter proximal end.
