1. An aspiration thrombectomy system, comprising:
a body configured to house components;
a vacuum source coupled to the body;
a vacuum valve at the body and fluidically coupled to the vacuum source, wherein the vacuum valve is configured to control a vacuum applied to a catheter system;
a vent valve at the body and configured to be fluidically coupled to a vent fluid, wherein the vent valve is configured to control vent fluid applied to the catheter system; and
a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle such that when a fluid column is in the catheter system the fluid column shifts distally and proximally, wherein the controller is configured to control distal displacement of the fluid column to a specific volume liquid that exits the catheter system distally before vacuum is reapplied thereby avoiding thromboembolic material from being uncontrollably ejected further distally within the blood vessel.
