Abstract

A gas (23) such as air or oxygen is forced into an aqueous fluid such as blood, plasma, blood extender fluids, or an imaging medium to form very small microbubbles (31) on the order or about 10 microns or less. The aqueous fluid within the microbubbles (31) therein is administered to the circulatory system of an animal. A catheter which allows for the infusion of the microbubbles containing fluid into the circulatory system of an animal is also disclosed.
