Abstract
This invention is a method and device for quickly removing thrombus from the vascular system, particularly from a saphenous vein graft which can have highly organized thrombus over its entire length. Thrombus is pulled into a chamber at the distal end of the thrombus extraction device as a result of negative pressure, a severing mechanism severs the portion of the thrombus that is in the chamber, and fluid under pressure is supplied to transport and dilute the blood and thrombus, which renders the thrombus more manageable and reduces the blood loss to the patient.
