Abstract
An aspiration thrombectomy system including an aspiration catheter, a vacuum source to provide negative pressure to the aspiration thrombectomy system, connection tubing to place the vacuum source and the aspiration catheter in fluid communication, controllable valves to control a level of negative pressure provided by the vacuum source, acoustic flow sensors to detect acoustic signals in the connection tubing, and a controller to receive, from the acoustic flow sensors, acoustic signals during a thrombectomy procedure, determine, based on the acoustic signals, whether occlusive material from a vasculature of a patient is lodged within the connection tubing or the aspiration catheter, and operate, automatically in response to determining that occlusive material is lodged based on the first acoustic signals, the aspiration thrombectomy system in a pulsed aspiration cycle by modulating one or more of the controllable valves to generate cyclical pressure pulses in the connection tubing and the aspiration catheter.
