A blood filter includes a hub, a plurality of legs, and a plurality of arms. Each of the legs includes a hook at a distal end thereof, a first linear segment extending substantially parallel to a hub longitudinal axis, a second linear segment extending obliquely with respect to the longitudinal axis
A blood filter includes a hub, a plurality of legs, and a plurality of arms. Each of the legs includes a hook at a distal end thereof, a first linear segment extending substantially parallel to a hub longitudinal axis, a second linear segment extending obliquely with respect to the longitudinal axis at a first angle, and an intermediate linear segment coupled to the first and second segments, the intermediate segment extending obliquely with respect to the longitudinal axis at a second angle less than the first angle. Each of the arms has a free end closer to the longitudinal axis than the hook of each of the legs. The free ends of the arms are spaced radially transverse to the longitudinal axis at substantially the same radial distance.
1. A filter delivery system, comprising: a blood filter including: a hub disposed along a longitudinal axis;at least one anchor projecting from the hub, the at least one anchor including a hook that penetrates a wall of the blood vessel, the hook being spaced along the longitudinal axis from the hub
1. A filter delivery system, comprising: a blood filter including: a hub disposed along a longitudinal axis;at least one anchor projecting from the hub, the at least one anchor including a hook that penetrates a wall of the blood vessel, the hook being spaced along the longitudinal axis from the hub, and spaced a first radial distance from longitudinal axis; andat least one locator projecting from the hub having at least a portion proximate a tip that engages the wall of the blood vessel, the tip being spaced along the longitudinal axis from the hub, and spaced a second radial distance from the longitudinal axis, the second radial distance being less than the first radial distance; anda delivery unit including: a first end coupled to a pusher pad via an elongate pusher, the elongate pusher having first, second, and third sections of different cross-sections between the first end and the pusher pad; anda slotted spline disposed between any two of the first, second, and third sections, the slotted spline having at least one groove extending along the longitudinal axis, the slotted spline having a reduced cross-section proximate the elongate pusher, each of the at least one groove receiving a portion of each of the at least one anchor. 2. The filter delivery system according to claim 1, wherein the first end of the delivery unit comprises a handle. 3. The filter delivery system according to claim 1, wherein the third section comprises a flexible wire having a smaller cross-section than the first and second cross-sections to assist in centering the filter in the blood vessel. 4. The filter delivery system according to claim 1, wherein the elongate pusher comprises a Nitinol wire. 5. The filter delivery system according to claim 1, wherein the slotted spline is located a distance from the pusher pad less than a length of the at least one anchor. 6. The filter delivery system according to claim 1, wherein the delivery unit further comprises a delivery tube surrounding a portion of the slotted spline.
