Patent number: 10413683Abstract: A device and method for dispensing a liquid with a gas includes an instrument having a cannula and a low-pressure tip. The low-pressure tip includes a tip housing that at least partially defines a high pressure chamber. A distal wall of the tip housing includes an aperture in fluid communication with the high pressure chamber. The low-pressure tip also includes a tube and a gas flow channel. The tube fluidly communicates liquid at a relatively low pressure from the cannula through the first aperture. The gas flow channel fluidly communicates gas from the cannula at a relatively high pressure and to the high pressure chamber for discharge from the aperture.
