CATHETER CLOG DETECTION IN THROMBECTOMY SYSTEMS

Abstract: a thrombectomy system includes an aspiration catheter configured for advancement through vasculature of a subject to facilitate clot removal from the vasculature of the subject. the thrombectomy system includes a fluid jet proximate to a distal end of the aspiration catheter. the thrombectomy system includes a flow direction sensor positioned on the aspiration catheter proximate to the fluid jet. the flow direction sensor is configured to detect a flow direction of fluid at a distal region of the aspiration catheter during operation of a clot removal state of the thrombectomy system. the flow direction of the fluid at the distal region of the aspiration catheter indicates a clog state of the aspiration catheter.
