摘要:
A vessel filter (10) comprising a first region and a second region wherein thefilter is movable between a collapsed position for delivery to the vessel andan expanded position for placement within the vessel. A first region has a filterportion (19) having a converging region (21) to direct particles toward the centerof the filter and having a plurality of spaced apart elongated struts (14) and,a plurality of connecting struts (14a, 14b) extending at an angle from the elongatedstruts to form closed geometric shapes (25). The second region is a flared region(17) in the expanded position to have a transverse dimension increasing towarda second end portion opposite the first end portion. The second region includesvessel engaging hooks (72a, 72b) at the second end portion. The filter has a pluralityof closed looped spacer struts (40) extending radially with respect to a longitudinalaxis of the filter when the filter is in the expanded position, positioned distallyof the filter portion.
