    Abstract: Aspiration thrombectomy devices and methods wherein an aspiration cycle includes a positive displacement segment to facilitate clot removal, a pump cartridge to facilitate tube management and an aspiration device for providing a vacuum surge. Disclosed herein is an aspiration thrombectomy system which relies on air or inert gas, rather than liquid, to provide both static and dynamic suction level profiles for safely and efficiently retrieving and removing from the body a thrombus. In one example embodiment, two or more pressure sources may be configured to apply two or more suction levels to an aspiration catheter. Valves may connect conduits between the pressure sources and the aspiration catheter, with the valves being selectively opened or closed to control which pressure level is applied to the catheter.
