Abstract: Generation of bubbles is disclosed to occur within a flow of an aqueous fluid. The bubbles may be formed within a tube of a selected diameter and the bubbles are controlled to exit the tube at a selected diameter. Generally, bubbles are formed to include a diameter of less than 1 millimeter, including less than about 20 microns.

Abstract: Disclosed is a system to generate bubbles. The bubbles may be formed to include a substantially or medically pure gas. The bubbles may be formed on demand and in a selected small size.

Abstract: Catheters for infusion of cardiovascular fluids into blood are disclosed. The cardiovascular fluid may, for example, comprise water highly supersaturated with a gas such as oxygen. Each catheter comprises one or more capillary tubings (or capillaries) through which a cardiovascular fluid flows. The distal end of each capillary is mounted (e.g., potted) preferably flush with an external surface of a catheter sidewall, while the proximal end of each capillary is in fluid communication with a cardiovascular fluid flowing through the lumen of the catheter. The combination of the catheter shape and the orientation of the distal end of each capillary relative to the longitudinal axis of the catheter provides control over the mixing pattern of the cardiovascular fluid with blood flowing within a vascular space such as an aorta.

Abstract: A liquid delivery device contains a liquid saturated with a gas in a pressure chamber pressurized to a selected amount. The liquid delivery device may be removed from the pressure chamber to deliver the saturated liquid to a volume.
