摘要：
A removable blood clot filter includes a number of locator members and anchormembers disposed radially and extending angularly downward from a hub. Thelocator members include a number of linear portions having distinct axesconfigured to place a tip portion approximately parallel to the walls of ablood vessel when implanted and to apply sufficient force to the vessel wallsto position the filter near the vessel centerline. The anchor members eachinclude a hook configured to penetrate the vessel wall to prevent longitudinalmovement due to blood flow. The hooks may have a cross section sized to allowfor a larger radius of curvature under strain so that the filter can beremoved without damaging the vessel wall.
