Abstract
A vessel filter having a first region and a second region, each having a mounting portion and a filter portion having a converging region at an end portion to direct particles toward the center of the filter. Each mounting portion is flared in the expanded position to have a transverse dimension increasing toward an end portion opposite the end portion of the converging region. A plurality of spaced apart struts extend between the first and second converging regions.
Claims22
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 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 mounting portion being flared in the expanded position to have a transverse dimension increasing in a direction away from the first portion, the second region having a second mounting portion and a second filter portion opening in the first direction and having a second converging region at a second portion to direct particles toward the center of the filter, the second mounting portion being flared in the expanded position to have a transverse dimension increasing in a direction away from the second portion, a plurality of spaced apart struts extending between the first and second converging regions.
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 flared region for mounting the filter, the second region formed by a second set of spaced apart struts forming a second filter portion having a second converging region and a second flared 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.
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 second mounting portion and a second filter portion opening in the first direction and having a second converging region at a second portion to direct particles toward the center of the filter, the second converging region being axially spaced from the first converging region, and adjacent struts of the first set of struts are interconnected by strut portions extending towards one another.
