Claim 17:
18. A method of generating microbubbles comprising:
providing a microbubble generator having (a) a syringe having a barrel filled with a body-compatible fluid, a plunger and a syringe tip; (b) a converging nozzle and an aerator; and (c) a housing surrounding the converging nozzle and the aerator to form an air chamber between an interior surface of the housing and exterior surfaces of the converging nozzle and the aerator, the air chamber circumferentially surrounding at least a portion of one of the converging nozzle and the aerator; wherein the converging nozzle has a coupling end, a converging tip opposite the coupling end, and an interior channel that fluidly couples the coupling end and the converging tip and has a diameter that progressively decreases from the coupling end to the converging tip, the converging nozzle coupled to the syringe tip at the coupling end; wherein the aerator has an inlet that is axially aligned with the interior channel and a discharge channel that is fluidly coupled to the inlet; the aerator further including one or more air channels that fluidly couple the air chamber and a region adjacent the converging tip and the inlet;
coupling the discharge channel to an intravenous line disposed in a patient undergoing a procedure; and
generating the microbubbles by forcing the body-compatible fluid out of the syringe and through the converging nozzle and the aerator, into the discharge channel.
