Abstract

A vessel filter comprising a first region and a second region wherein the filter is movable between a collapsed position for delivery to the vessel and an expanded position for placement within the vessel. A first region has a filter portion having a converging region at a first end portion to direct particles toward the center of the filter and the second region is flared in the expanded position to have a transverse dimension increasing toward a second end portion opposite the first end portion. The second region includes a vessel engaging portion at the second end portion. The second region includes a plurality of spaced apart struts with adjacent struts being joined.

Claims (9)

1. A vessel filter comprising a first region and a second region, the first region including a filtering section for capturing particles and having a first transverse dimension, the second region including a mounting section for mounting the filter within the vessel, the mounting section having a second transverse dimension greater than the first transverse dimension and including vessel engaging structure to retain the filter, the vessel engaging structure including a first set of hooks and a second set of hooks, each set of hooks being positioned at an end of the mounting section, each of the hooks of the first set of hooks having a maximum transverse dimension greater than a maximum transverse dimension of each of the hooks of the second set of hooks.

2. The vessel filter of claim 1 , wherein the mounting section includes a plurality of struts and one of the hooks extends from a terminal end of the strut, the terminal end of each strut defining a first plane and each hook extending from the strut lying in the first plane of the strut.

3. The vessel filter of claim 2 , wherein plurality of struts includes a first set of struts axially offset from a second set of struts.

4. The vessel filter of claim 3 , wherein the filter is formed from a laser cut tube, the tube cut to form a set of struts, wherein each of the hooks of the second set of hooks are formed of a transverse dimension substantially corresponding to a transverse dimension of one strut and each of the hooks of the first set are formed of a transverse dimension substantially corresponding to a transverse dimension of two adjacent struts.

5. The vessel filter of claim 3 , wherein an outer surface of the second set of hooks substantially conforms to an inner surface of the first set of hooks.

6. The vessel filter of claim 1 , wherein the mounting section includes a first and a second set of struts and the first set of struts is axially offset from the second set of struts.

7. The vessel filter of claim 6 , wherein the filter is formed from a laser cut tube, the tube cut to form a set of struts, wherein each of the hooks of the second set of hooks are formed of a transverse dimension substantially corresponding to a transverse dimension of one strut and each of the hooks of the first set are formed of a transverse dimension substantially corresponding to a transverse dimension of two adjacent struts.

8. The vessel filter of claim 1 , wherein the filter is formed from a laser cut tube, the tube cut to form a set of struts, wherein each of the hooks of the second set of hooks are formed of a transverse dimension substantially corresponding to a transverse dimension of one strut and each of the hooks of the first set are formed of a transverse dimension substantially corresponding to a transverse dimension of two adjacent struts.

9. The vessel filter of claim 1 , wherein an outer surface of the second set of hooks substantially conforms to an inner surface of the first set of hooks.
