Abstract
An apparatus is provided to deliver carbon dioxide to an animal in a manner which allows the carbon dioxide to totally displace blood in an area of interest and to thus serve as a contrast media for angiographic procedures, or blood displacement media for angioscopic or laser procedures. The apparatus enables the carbon dioxide to flow at varied flow rates, the varied flow rates correlated to the varied flow rate of blood in the animal's vascular system. The flow rate of the carbon dioxide is variable during the course of a single injection.
