摘要：
A vascular filter device comprises a support and a filter comprising one or more filter elements configured to capture thrombus passing through a blood vessel. A holder holds the filter in a closed filtering state and releases to convert the filter to an open state after a period of time. The filter is adapted to retain thrombus after said conversion. In one case the filter elements are arranged to remain in a closed state after released by the holder, because they are blocked by a retained clot from opening fully, and the filter elements are biased to the open state with a bias level which is counter balanced by force exerted by a retained clot under action of blood flow.
