Patent ID: 7901373

Claim:
A device for abrading tissue having a distal end and a proximal end, which includes: a) a gas inlet port connected to a pressurized gas source; b) a liquid inlet port connected to a pressurized liquid source; and c) a mist jet delivery nozzle arrangement including i) at least one gas discharge nozzle arranged to receive a flow of pressurized gas from said gas inlet port and configured to accelerate the flow of gas so as to discharge it into the atmosphere at an elevated velocity at said distal end of said device so that the gas flow undergoes a rapid and substantial reduction in pressure to atmospheric pressure; and ii) at least one liquid discharge nozzle arranged to receive a flow of liquid from said liquid inlet port and configured and operative to discharge the flow of liquid at a point past said distal end of said device into the elevated velocity flow of gas, thereby to similarly accelerate a velocity of the discharged liquid as a mist of accelerated droplets.
