Abstract
A vascular filter system comprises a vascular filter (1), a clamp device (50), and a delivery catheter (51). The filter (1) comprises filter elements (6). When used without the clamp device (50), the filter elements (6) move from a closed state to an open state upon elapse of a predetermined period of time. In the closed state the filter elements (6) capture thrombus passing through the inferior vena cava (2). The delivery catheter (51) is employed to deliver the clamp device (50) to the filter (1) after the filter (1) has been deployed in the inferior vena cava (2). The clamp device (50) engages with the filter elements (6) of the filter (1) to clamp the filter (1) in the closed state beyond elapse of the predetermined period of time. Because of the presence of the clamp device (50), the filter elements (6) are no longer free to move from the closed state to the open state upon elapse of the predetermined period of time. In this manner the period of time in which the filter (1) captures thrombus is extended either temporarily or permanently.
