Abstract

See full text

A thrombus filter configured for placement within a blood vessel lumen. The filter having a longitudinal axis. The filter includes first and second units, each unit including a plurality of elongated struts. Each strut has a joining end where the respective struts of each unit are joined together. Each strut also has a free end opposite the joining end. The struts have at least two curves such that in a longitudinal planar projection of the filter, each strut has a first direction of curvature proximate the joining end and an opposite direction of curvature closer to the free end. In a transverse planar projection of the filter, the strut has a first direction of curvature proximate the joining and an opposite direction of curvature closer to the free end. The units can be coupled together in opposition such that the free ends of the struts of the first unit are generally oriented in a first longitudinal direction and the free ends of the struts of the second unit are generally oriented in the opposite longitudinal direction.
