Abstract
An aspiration thrombectomy system for use with a vacuum source and an aspiration catheter includes a connection tubing configured to selectively connect the aspiration catheter to the vacuum source via a controllable vacuum valve. A distal pressures sensor is configured to detect pressure at the distal end within the connection tubing. An automatic controller may operate the vacuum valve to generate fluid pressure change in the connection tubing, and detect pressure profiles in the connection tubing correlated with the generated pressure changes via the distal pressure sensor. The automatic controller may determine one or more system states in the aspiration catheter or connection tubing based on the detected pressure profiles, and may operate the vacuum valve based on the determination of system state.
