1. A filter for a body lumen, comprising:
- a first axial portion adjacent a first end of the filter;
a second axial portion adjacent a second end of the filter;
a plurality of struts disposed between and coupled to the first and second axial portions, each strut comprising;
a first apex;
a second apex offset a longitudinal distance from the first apex;
a first portion extending between the first axial portion and the first apex, the first portion of the strut comprising;
a first leg; and
a second leg, wherein the first leg and the second leg each extend from a branch point to the first axial portion; and
a transition portion disposed between the first apex and the second apex, the transition portion disposed radially inward from the first and second apexes.

Abstract
A filter, configured to be disposed within a body lumen, such as within the vasculature. The filter may include a plurality of struts, configured to interact with the body lumen wall in order to stabilize the position of the filter and to create a filtering structure. Each strut may have two or more apexes configured to contact the body lumen wall. In some embodiments the filter may be integrally formed form a single tube of material.
