Abstract
An aspiration thrombectomy system including an aspiration catheter having a proximal end and a distal end, the aspiration catheter having a lumen to accommodate fluid, a vacuum source including a controllable vacuum valve, a tubing connected to the aspiration catheter, and a controller configured to detect a change in a catheter diameter corresponding to a change in the connection between the aspiration catheter and the tubing. The controller is configured to change a pulsation protocol associated with the aspiration catheter responsive to the change in the catheter diameter, and 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.
