    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.

    摘要: A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The first region includes a plurality of spaced apart elongated struts with adjacent struts being joined.

    摘要: A vessel filter comprising a mounting section having first and second ends and a first and second filtering section. The filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. In the expanded position a first end of the first filtering section converges to form a first converging region and a second end of the second filtering section converges to form a second converging region. The first converging region is positioned radially and axially inwardly of the first end of the mounting section and the second converging region is positioned radially and axially inwardly of the second end of the mounting section.

    摘要: A vein filter movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. The first region of the filter has a mounting portion for mounting the vessel filter within the vessel and a first filter portion converging to form a first converging region at a first end portion, positioned radially and axially inwardly of an end of the mounting portion. The second region of the filter has a transverse dimension decreasing toward a second end portion opposite the first end portion to form a second filter portion at the second end portion on the opposing side of the filter from the first filter portion.
