Patent ID: 8920458

Claim:
A vessel filter comprising a body cut from a tube, the tube having a first diameter, the body being integral and having a first region and a second region, the body movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel, the first region having a first set of spaced apart struts forming a first filter portion having a first converging region converging into a first tubular portion and a first mounting region for mounting the filter, the first set of struts integral with and emanating from the first tubular portion, the second region formed by a second set of spaced apart struts, the second region having a second converging region converging into a second tubular portion axially spaced from the first tubular portion, the second set of struts being positioned proximal of the first set of struts, the second set of struts integral with and emanating from the second tubular portion, the first and second set of struts being connected by a plurality of longitudinally extending struts extending between the first and second tubular portions, the longitudinally extending struts emanating from the first tubular portion and extending into the second tubular portion such that the second tubular portion is positioned between and separates the second set of struts from the longitudinally extending struts, and the first and second sets of struts extending in a first direction, wherein in an initial position, a transverse dimension of the first set of struts, a transverse dimension of the second set of struts and a transverse dimension of the longitudinal struts does not exceed the first diameter of the tube.
