Abstract
A dynamic aspiration system includes a connecting tube, a vacuum source, a pressure source, an aspiration catheter, a first controllable valve to control a level of negative pressure provided by the vacuum source, a second controllable valve to control a level of positive pressure provided by the pressure source, pressure sensors, and a controller. The controller modulates the controllable valves to generate pressure pulses, determines, for each of the pressure pulses, a degree of success corresponding to a change in a flow in the aspiration catheter or the connecting tube responsive to the pressure pulse, identifies one or more first pressure pulses determined to have the highest degrees of success, and modulates the controllable valves to generate the first pressure pulses in one or more pressure pulse cycles.
