Removable thrombus filter
First Claim
1. A thrombus filter for placement within a blood vessel lumen, having a longitudinal axis, the filter comprising:
- first and second units,a first wire having two ends, the first wire extending from said first unit in a first direction to one of the ends,a second wire having two ends, the second wire extending from said second unit in a second direction to one of the ends opposite to said first direction; and
means for detachably coupling said first an second wires.

Abstract
A thrombus filter configured for placement within a blood vessel lumen. The filter having a longitudinal axis. The filter includes first and second units, each unit including a plurality of elongated struts. Each strut has a joining end where the respective struts of each unit are joined together. Each strut also has a free end opposite the joining end. The struts have at least two curves such that in a longitudinal planar projection of the filter, each strut has a first direction of curvature proximate the joining end and an opposite direction of curvature closer to the free end. In a transverse planar projection of the filter, the strut has a first direction of curvature proximate the joining and an opposite direction of curvature closer to the free end. The units can be coupled together in opposition such that the free ends of the struts of the first unit are generally oriented in a first longitudinal direction and the free ends of the struts of the second unit are generally oriented in the opposite longitudinal direction.

13. A thrombus filter for placement within a blood vessel, having a longitudinal axis, the filter comprising:
-
first and second units, each including a plurality of elongated struts, each strut having a joining end and a free end, wherein the respective struts of each unit are joined together generally about the longitudinal axis of the filter at the joining ends, the first and second units being coupled in opposition such that the free ends of the first unit struts are generally oriented in a first longitudinal direction and the free ends of the second unit struts are oriented generally in the opposite direction, a first wire having two ends, the first wire extending from said first unit in a first direction to one of the end, a second wire having two ends, the first wire extending from said second unit in a second direction opposite to said first direction to one of the ends; and means for detachably coupling said first and second wires. - View Dependent Claims (14, 15, 16, 17, 18)
