Abstract: The present invention embodies a method and an injector adapted to incorporate this method, for keeping a patient's vein open during an intravenous contrast injector procedure without injecting a saline solution from a separate syringe. The injector includes a controller having a programable software module to allow an operator to configure the injector to push some contrast media fluid through an injection site and then retract a plunger drive ram.

Alternatively, the syringe is adapted with an elastic plunger which as it enlarges and contracts facilitates fluid communication through the injection site. Additionally, the plunger drive ram can be adapted to gradually pull as well as push the plunger, thereby causing fluid to flow across the injection site.
