摘要：A vacuum aspiration control system for u with a vacuum source and an aspiration catheter includes a connecting tube configured to connect the vacuum source
with a lumen of an aspiration catheter. An on-off valve is operatively coupled to the connecting tube, and a nsing unit is configured to detect flow within the connecting tube and provide a signal reprentative of flow. A controller receives the signal to decide whether to open or clo the valve. The controller may automatically clo the valve to stop flow when flow through the connecting tube is unrestricted, or according to a predetermined timing quence. The controller can further periodically open a clod valve to determine whether flow has entered an acceptable range. The controller can still further engage puld aspiration with a pressure manipulation asmbly when flow is restricted or occluded.
