Abstract
The present invention is directed to a manually actuated aspiration device, aspiration system and a method of use to enable and facilitate en bloc removal of undesirable intravascular material, including, but not limited to, thrombus, embolus, or vegetation through a working lumen of a suction cannula during minimally invasive percutaneous procedures. The aspiration device includes valves oriented in opposite direction to control the fluid flow through the aspiration system and into a waste collection component. Alternatively, the aspiration system further comprises a filter that removes undesirable intravascular material prior to reinfusing blood into a patient's vasculature.
