More Information
Summary:An apparatus is configured to provide hemostasis with tissue removal in order to inhibit one or more of blood loss or tissue drainage. In many embodiments, a nozzle releases a liquid jet in a liquid medium in order to provide cavitation and a plurality of shedding pulses. The liquid jet, its cavitation and the plurality of shedding pulses can affect vascular tissue in order to promote clotting in order to inhibit bleeding. In many embodiments, vessels of the vascular tissue are affected at a distance from a region where cavitation of the water jet contacts the tissue. In many embodiments, the cavitation and plurality of shedding pules are related to a pulsatile shear wave propagating along the blood vessel that is related to clot promoting changes of the blood vessel.
