Abstract:
1. A vessel filter comprising a tubular member having a distal portion and a proximal portion, a longitudinal axis and a plurality of elongated cutouts formed therein extending along the longitudinal axis and forming a series of elongated spaced apart struts separated by the cutouts, the filter movable between a first insertion configuration and a second deployed configuration, each of the spaced apart struts in the deployed configuration forming longitudinally extending linear struts extending substantially parallel to the longitudinal axis of the filter to form a mounting section and each including a first inwardly bent region at a first end bending towards a center of the filter to transition to a first filter section and a second inwardly bent region at a second end bending towards a center of the filter to transition to a second filter section, the first inwardly bent region transitioning into a linear strut region, the linear strut region transitioning into a first curved region curving away from the center of the filter, and the second inwardly bent region transitioning into a linear strut region, the linear strut region transitioning into a second curved region curving away from the center of the filter, the first curved region extending into an inner portion of a first tubular portion and the second curved region extending into an inner portion of a second tubular portion, the inner portion of the first and second tubular portions being the portions closer to the center of the filter, the first bent region positioned distal of the first tubular portion and the second bent region positioned proximal of the second tubular portion such that a first imaginary line tangent to the first bent region of the struts and perpendicular to the longitudinal axis does not intersect the first tubular portion and a second imaginary line tangent to the second bent region of the struts and perpendicular to the longitudinal axis region does not intersect the second tubular portion such that the first imaginary line is distal of the first tubular portion and the second imaginary line is proximal of the second tubular portion.
