1. A withdrawal member for a filter for the vena cava, the filter having a cap and shape memory or shaped strands forming a tail, said strands being fixed to the cap and located on the same side of the cap, said withdrawal member comprising side by side and in the following order: a rod with a distal end; a flexible region; a distal tube; and a plurality of resilient arms; wherein (i) the distal tube has a first end and a second end, the first end being the farther from the distal end of the rod and the second end the closer from the distal end of the rod, (ii) the plurality of resilient arms flares from the first end of the distal tube, said resilient arms naturally spaced apart from each other and ending in hooks directed inward so as to grip the cap of the filter upon tightening, (iii) the flexible region is adjacent the second end of the distal tube and spaced from the plurality of resilient arms by the distal tube; and (iv) the flexible region is in a bent position when it is not strained, such that a longitudinal axis of the distal tube and a principal axis of the rod form an angle (α) different front 180°.
