Hemostasis and tissue removal using pulsatile liquid jet
The granted patent US12053202B2 outlines a novel method for treating tissue through the application of a liquid jet directed at the tissue to create pulsatile shear waves. This method involves using a nozzle to generate these shear waves, which facilitate the removal of tissue. The claims specify that the jet can be abrasive, allowing for the simultaneous removal of both vascular and non-vascular tissue at comparable rates. Additionally, the positioning of the nozzle is critical; it must be placed at a distance greater than a defined transition threshold to selectively target non-vascular tissue while minimizing the removal of vascular structures.
Further claims detail the mechanics of the method, including the generation of shedding pulses that contribute to the formation of the pulsatile shear waves. These pulses can be produced by various means, such as pump pulses or specific hydrodynamic parameters of the jet, which include fluid jet velocity and shear stress fields. The configuration of these parameters is essential, as they influence the frequency and characteristic length of the shedding pulses, ultimately affecting the efficiency and selectivity of the tissue removal process. This innovative approach presents a potential advancement in tissue treatment methodologies, emphasizing precision and control in the removal of targeted tissue types.
