Abstract
An aspiration thrombectomy system, comprising an aspiration catheter having a proximal end and a distal end, wherein the proximal end of the aspiration catheter comprises a lumen configured to accommodate fluid, a vacuum source comprising a controllable vacuum valve, and a controller configured to detect a change in a connection between the aspiration catheter and the aspiration thrombectomy system, wherein the controller is further configured to change a pulsation protocol associated with the aspiration catheter responsive to the change in the connection between the aspiration catheter and the aspiration thrombectomy system, wherein the pulsation protocol specifies pressure variations and pressure patterns to modulate the vacuum valve to change a level of vacuum at the distal end of the aspiration catheter.
