Abstract
A medical filter has more than one pair of struts extending along an undulating path between a first and second end, which cooperate to define a first and second filter element having a plurality of cells, connected by a central portion with longitudinal strut sections. The struts extend between the first and second ends, and the struts tend to resiliently expand in radially outward directions from a compressed initial shape to an expanded deployed shape. In the expanded shape, the undulating path is defined by (i) a first portion of each pair of ribs extends substantially adjacent to each other for a distance from the first end, (ii) a second portion of each pair of ribs extends substantially adjacent to each other for a distance from the second end; and (iii) an intermediate portion of each one of a pair of ribs extends to curve away from each other.
