Abstract
An aspiration thrombectomy system includes a vacuum source, a catheter having a proximal end and a distal end, a junction fluidically connected to the proximal end of the catheter, a sensor to detect flow through the proximal end of the catheter or the junction and produce a flow signal, a vacuum valve fluidically connected to the junction and to the vacuum source, and a controller. The controller may receive the flow signal and modulate the vacuum valve based on the signal. The controller may have a sampling state in which the vacuum valve is not held fully open for a period of time and at least one aspiration state in which the vacuum valve is fully open. The controller may idle in the sampling state in response to the signal indicating open flow, and transition to an aspiration state in response to the signal indicating a clot or thrombus.
