摘要： An aspiration thrombectomy system includes a thrombectomy catheter assembly that maintains pulsatile energy of cyclic aspiration while the catheter is occluded. A system configuration includes a catheter, vacuum and vent fluid sources respectively connected to vacuum and vent valves, a vent catheter valve connecting a catheter lumen to the vent fluid source, a manifold connected to the catheter and vacuum and vent valves, a pressure sensor upstream of the vacuum valve, and a controller configured to operate the vacuum, vent, and vent catheter valves, receive sensor pressure data, control the vent catheter valve dependent upon the data. Determination can be upon decrease of pressure waveform amplitude. An operable lumen of the system includes a volume of the catheter lumen and an interior of the manifold up to an input of the vacuum valve input and an output of the vent valve.
