Disclosed is an apparatus comprising: a hose extending, in use, from an automated syringe to a free end; an angiographic catheter; a syringe; and valve having a first port coupled to the catheter, a second port coupled with the syringe and a third port coupled hose free end, the valve being manipulable to connect any two of its ports to one another for communication such that, in use, when the syringe is evacuated, the automated syringe and the apparatus up to the catheter are charged with CO2 and the catheter is inserted into the vascular system of a patient, the valve (i) can be manipulated to connect the syringe to the catheter such that withdrawal of the plunger of the syringe purges the catheter and (ii) thereafter can be manipulated to connect the catheter to the hose such that evacuation of the automated syringe injects CO2 into said vascular system.
