1. An aspiration thrombectomy system, comprising:
a catheter system including an aspiration catheter having a proximal portion, a distal end and a lumen extending through the aspiration catheter;
a vacuum source fluidically coupled to the catheter system;
a vacuum valve fluidically coupled to the vacuum source and the proximal portion of the aspiration catheter to control a vacuum flow in the catheter lumen;
a vent valve fluidically coupled to the proximal portion of the aspiration catheter, the vent valve being configured to control a flow of a vent fluid in the catheter lumen; and
a controller configured to
(1) perform a purge cycle to remove air in the catheter system in which the vent valve is opened while the vacuum valve is closed such that vent fluid flows through catheter system thereby removing air from the catheter system, and
(2) after performing the purge cycle, open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.
