Figure 48 - Carbon dioxide digital subtraction angiography (CO2 DSA): A comprehensive user guide for all operators

Figure 48. AngiAssist (AngioAdvancements) utilizes a reservoir and delivery syringe with a oneway valve on the receiving and delivery end of the tubing. Carbon dioxide goes to the reservoir syringe and the one-way valve prevents backflow. Carbon dioxide can then be advanced into the delivery syringe after turning the K-valve. The K-valve can be turned again and product delivered. The one-way valve prevents backflow. This system is approved for gaseous delivery but not for intravascular therapy.
