Claim Text:
1. A vessel filter comprising: a tubular region; a plurality of elongated struts extending initially linearly distally from the tubular region and then angling outwardly away from a longitudinal axis of the filter forming a concave region, the plurality of elongated struts including at least first, second and third filter struts; a first connecting strut extending from the first filter strut along its length at an angle in a first direction, the first direction being at an angle to the longitudinal axis of the filter; a second connecting strut extending from the second filter strut along its length at an angle in a second direction toward the first connecting strut, the second direction being at an angle to the longitudinal axis of the filter and different than the first direction, the first and second connecting struts extending to converge toward each other along their entire lengths to come together at a first joining region forming a first closed geometric shape; a third connecting strut extending from the first filter strut at an angle away from the first connecting strut; a fourth connecting strut extending from the third filter strut at an angle toward the third connecting strut, the third and fourth connecting struts coming together at a second joining region forming a second closed geometric shape; and an elongated mounting strut extending distally from each of the first and second joining regions and having a vessel engaging hook extending therefrom, the elongated mounting struts being unconnected and terminating in free ends.
