초록 ▼

A vessel filter movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel, and having a filter portion having a converging region to direct particles toward the center. The filter portion converges into a tubular portion. The second region is flared in the expanded position to have a transverse dimension increasing in a direction away from the filter portion and includes a vessel engaging portion. The first region has a spacer to keep the filter more toward a center of a vessel, wherein in the collapsed position the spacer extends axially in an elongated position cranially of the cranial end of the filter and in the expanded position the spacer forms a looped region extending radially with respect to a longitudinal axis of the filter. The spacer has a first end attached to the internal surface of the tubular portion and extends within the tubular portion and emerges cranially from the tubular region to form the looped region.

1. A vessel filter comprising a first region and a second region, the filter movable between a collapsed position for delivery to a vessel and an expanded position for placement within the vessel, the first region having a filter portion having a converging region to direct particles toward a center of the filter, the filter portion converging into a tubular portion, the tubular portion having an internal surface, the filter terminating at a cranial end, the second region being flared in the expanded position to have a transverse dimension increasing in a direction away from the filter portion toward a caudal end, the second region including a vessel engaging portion, the first region having a spacer to keep the filter more toward a center of the vessel upon placement of the filter within the vessel, the spacer having a first end and a second end, the second end fixedly attached to the internal surface of the tubular portion, the first end extending within the tubular portion and emerging cranially from the tubular portion, wherein in the collapsed position of the filter the first end extends axially in an elongated position cranially of a cranial end of the tubular portion and in the expanded position of the filter the first end extends radially and helically with respect to a longitudinal axis of the filter and transitions to a substantially planar looped region. 2. The vessel filter of claim 1, wherein the first region includes a plurality of spaced apart elongated struts and a plurality of connecting struts extending at an angle from the elongated struts. 3. The vessel filter of claim 1, wherein the looped region extends beyond a cranial edge of the tubular portion in the expanded position of the filter. 4. The vessel filter of claim 1, wherein the looped region encircles the tubular portion of the filter in the expanded position of the filter. 5. The vessel filter of claim 1, wherein the tubular portion includes a retrieval structure for removal of the filter. 6. The vessel filter of claim 1, wherein the spacer has a cranial end terminating in a retrieval structure for removal of the filter. 7. The vessel filter of claim 6, wherein the retrieval structure includes a hook. 8. The vessel filter of claim 1, wherein the filter is formed from a laser cut tube and composed of shape memory material. 9. The vessel filter of claim 1, wherein the looped region has a transverse dimension which does not exceed a transverse dimension of a caudal end of the filter in the expanded configuration. 10. The vessel filter of claim 1, wherein the looped region of the spacer approximates a circle centered on the longitudinal axis of the filter. 11. The vessel filter of claim 1, wherein the looped region of the spacer curves at least 360 degrees.
