Abstract

A flow modulation device 300 for controlling a rheological state of a dispensed pressurized fluid includes a porous element 304 and an exit tube. The porous element 304 is in fluid communication with a distal end of an outlet tube 303 and receives pressurized fluid in a first rheological state. The porous element 304 includes a plurality of channels that divide a flow channel into a plurality of flow paths through which the pressurized fluid flows and that modulates the flow of the pressurized fluid. The exit tube 305 includes proximal end 355 and distal end 345 and an intermediate body including a sidewall 365 defining a hollow internal lumen 375. The exit tube 305 is in fluid communication with the porous element 304 and receives the modulated pressurized fluid from the plurality of flow paths and refocuses the fluid to dispense the pressurized fluid in a second rheological state.
