Vein filter
First Claim
1. A vessel filter comprising a first region and a second region, the filter 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 struts forming a first mounting portion and a first filter portion opening in a first direction, the filter portion having a first converging region at a first portion to direct particles toward the center of the filter, the mounting portion being flared in the expanded position to have a transverse dimension increasing toward a second portion opposite the first portion, the second region having a second set of struts forming a second mounting portion being flared in the expanded position and opening in the first direction, a plurality of spaced apart struts extending between the first and second regions.

Abstract
A vessel filter having a first region having a first set of struts forming a mounting portion and a filter portion having a converging region at a first portion to direct particles toward the center of the filter. The mounting portion is flared in the expanded position to have a transverse dimension increasing toward a second portion opposite the first portion. A second set of struts forms a second mounting portion flared in the expanded position. A plurality of spaced apart struts extend between the first and second regions.

- 13. A vessel filter comprising a body cut from a tube, the body having a first region and a second region and being movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel, the first region of the filter having a first set of spaced apart struts forming a first filter portion having a first converging region and a first mounting region for mounting the filter, the second region formed by a second set of spaced apart struts forming a second mounting region for mounting the filter, the second set of struts being positioned distal of the first set of struts, the first and second set of struts being connected by at least one longitudinally extending strut and both sets of spaced apart struts being oriented in a first direction.
- 18. A vessel filter comprising a first region and a second region, the filter 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 struts and having a first mounting portion and a first filter portion opening in a first direction and having a first converging region at a first portion to direct particles toward the center of the filter, the second region having a second set of struts having a second mounting portion, and adjacent struts of the first set of struts are interconnected by strut portions extending towards one another.
