Abstract
An intravascular filter comprising a plurality of struts extending from a central hub. The distal ends of the struts are curved to form an anchor to the vessel wall. The hub has a hook for retrieving the filter. The filter may be removed by employing a torque force to the hook, so as to disengage the strut ends from the vessel wall.
