摘要：
A vessel filter having a first region and a second region, the filter movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. The first region has a filter portion having a converging region to direct particles toward the center of the filter and includes a plurality of spaced apart filter struts. The struts each have a strut height defined as a distance between a first wall and a second wall. A plurality of hooks are at the second region, the hooks having a vessel penetrating tip and a width greater than the width of the strut from which it extends such that the penetrating tip portion of the hook extends beyond the first wall.
