An inferior vena cava filter ( 340 ) for use in the inferior vena cava ( 4 ) to capture thrombus ( 8 ) passing through the inferior vena cava ( 4 ) towards the heart and lungs to prevent pulmonary embolism comprises a proximal support hoop ( 302 ), a distal support hoop ( 312 ) and a plurality of support struts ( 303 ) extending between the proximal support hoop ( 302 ) and the distal support hoop ( 312 ). The filter ( 340 ) also comprises a plurality of capture arms ( 121 ) which are movable from a capturing configuration to an open configuration. The capture arms ( 121 ) are biased towards the open configuration. A biodegradable suture holds the capture arms ( 121 ) in the capturing configuration.
