  • Publication number: 20210128182
    Abstract: A vacuum aspiration control system for use 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 sensing unit is configured to detect flow within the connecting tube and provide a signal representative of flow. A controller receives the signal to decide whether to open or close the valve. The controller may automatically close the valve to stop flow when flow through the connecting tube is unrestricted, or according to a predetermined timing sequence. The controller can further periodically open a closed valve to determine whether flow has entered an acceptable range. The controller can still further engage pulsed aspiration with a pressure manipulation assembly when flow is restricted or occluded.

  • Publication number: 20200330117
    Abstract: A system for intracranial access that includes a support assembly is described. The system includes a tubular probe shaft that may be advanced through a hole in the patient's skull. The tubular probe shaft houses a rotating element that cuts clot, and is connected to a vacuum source to aspirate clot fragments and blood from the site. The rotating element may have a bident shape.
