Abstract
An aspiration thrombectomy system, comprising a vacuum source comprising a controllable vacuum valve, a pressure source comprising a controllable pressure valve, an aspiration catheter having a proximal end and a distal end, wherein the proximal end of the aspiration catheter comprises connection tubing having a lumen configured to accommodate fluid, and wherein the connection tubing acts as a common conduit for fluid communication between the aspiration catheter and the vacuum and pressure sources via the vacuum and pressure valves, respectively, and a controller configured to open and close the vacuum and vent valves in a predetermined cycle to change a level of vacuum at the distal end of the aspiration catheter and control flow in and out from the distal end of the catheter.
