1. A thrombectomy system comprising:
an aspiration catheter having a guidewire lumen, an aspiration lumen, and a high pressure irrigation lumen, the aspiration catheter having a proximal end and a distal end; and
a control box fluidly connected to the aspiration catheter and configured to synchronously provide irrigation and vacuum through the aspiration catheter, the control box comprising a one-way pressure/vacuum valve configured to eliminate the possibility of turning the vacuum on without activating the irrigation, a connecting conduit within the control box extending from the one-way pressure/vacuum valve to a high pressure irrigation conduit in fluid communication with the high pressure irrigation lumen.
