Patent ID: 6849235

Claim:
A method for gas-supersaturating fluid comprising the acts of: providing a fluid supply and a gas supply; providing a chamber having a first inlet, a second inlet, a third inlet and an outlet; providing a piston assembly coupled to receive fluid from the fluid supply and to deliver the fluid to the second inlet and to the third inlet of the chamber; providing, a nozzle coupled to the third inlet of the chamber to deliver the fluid from the piston assembly to the chamber; providing a first valve coupled to the outlet of the chamber, the first valve being coupled to an actuator assembly to control delivery of gas-supersaturated fluid from the chamber; providing a second valve coupled to the second inlet, the second valve being coupled to an actuator assembly to control dilution during the creation of gas-supersaturated fluid within the chamber; and providing a third valve coupled to a fluid lumen through which fluid from the piston assembly flushes, bypassing the chamber, when the third valve is open and the first valve and the second valve are closed.
