摘要：
Target tissue may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the tissue to soften, liquefy, or gellify. The tissue that has been softened, liquefied, or gellified is then suctioned away.
