摘要：
A vessel filter comprising a first distal region terminating at a first end and a second proximal region terminating at a second end of the filter and 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. The second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the filter portion and includes a vessel engaging portion at the second end portion. The first region has a retrieval hook and a spacer forming a looped region extending radially from the first region.
