Method and process for generating a high repetition rate pulsed microjet

Abstract

A system and method for producing a high repetition pulsed microjet for use in medical applications. The device includes a stagnation chamber and a hydraulic pump for pumping a sterile fluid into the stagnation chamber. A flexible walled volume disposed in the stagnation chamber and filled with a hydraulic fluid. The hydraulic piston is cyclically displaced towards/away from the stagnation chamber thereby increasing/decreasing the pressure of the hydraulic fluid on the flexible walled volume. In turn, the flexible walled volume is compressed and the sterile fluid is expelled through an orifice in the flexible walled volume under pressure producing the pulsed microjet. This process may be repeated to produce repetitive pulsed microjets. In addition, the flow conduction of the hydraulic fluid between the hydraulic pump and stagnation chamber may be controlled by inserting a blocking device therebetween.
