A filter (20) comprises an inner, anchoring basket (10) arranged concentrically inside an outer, alignment basket (12). The anchoring basket (10) comprises a plurality of anchoring struts (38) terminating in barbs (54). The alignment basket (12) includes a plurality of alignment struts (40), which terminate downstream of the anchoring struts (38). A lumen (18) is provided through hubs (14, 16) of the filter (20) so that the filter (20) can be deployed over a guidewire (66). |
