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 blood filter, comprising: a hub extending in a hub direction from a first hub end to a second hub end along a longitudinal axis;a plurality of legs extending away from the second hub end along the longitudinal axis, each of the legs including: a hook at a distal end thereof;a first linear segme
1. A blood filter, comprising: a hub extending in a hub direction from a first hub end to a second hub end along a longitudinal axis;a plurality of legs extending away from the second hub end along the longitudinal axis, each of the legs including: a hook at a distal end thereof;a first linear segment extending substantially parallel to the longitudinal axis;a second linear segment extending obliquely with respect to the longitudinal axis at a first angle; andan 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; anda plurality of arms extending away from the second hub end along the longitudinal axis, each of the arms having a first end and a free end, the first end of each arm contiguous to a portion of the leg, the free end of each of the arms being closer to the longitudinal axis than the hook of each of the legs, the free ends of the plurality of arms being spaced radially transverse to the longitudinal axis at substantially the same radial distance. 2. The blood filter according to claim 1, wherein the plurality of arms comprise at least four arms with four corresponding free ends disposed around the longitudinal axis to define a polygon about the longitudinal axis. 3. The blood filter according to claim 1, wherein the plurality of arms comprise six arms with six free ends disposed on a generally circular perimeter about the longitudinal axis. 4. The blood filter according to claim 3, wherein the hub comprises a generally cylindrical member that surrounds a proximal end of each of the legs and the first end of each of the arms. 5. The blood filter according to claim 3, wherein the plurality of arms comprises at least four arms disposed over generally equal angular intervals and the plurality of legs comprises at least four legs disposed over generally equal angular intervals. 6. The blood filter according to claim 5, wherein the angular interval comprises about 60 degrees about the longitudinal axis. 7. The blood filter according to claim 3, wherein each of the arms comprises a portion disposed between the first end and the free end so that at least two arms are disposed diametrically with respect to the longitudinal axis and approximate a generally planar cross-section of an inverted cup. 8. The blood filter according to claim 7, wherein the free ends of the at least two arms define a diameter smaller than a diameter defined by terminal ends of the hook of at least two legs disposed diametrically with respect to the longitudinal axis. 9. The blood filter according to claim 7, wherein the portion comprises an inner arm portion and an outer arm portion located further away from the longitudinal axis than the inner arm portion, the inner arm portion extending at a first angle with respect to the longitudinal axis, the outer arm portion extending at a second angle with respect to the longitudinal axis greater than the first angle. 10. The blood filter according to claim 9, wherein the second angle comprises about forty-five degrees with respect to the longitudinal axis. 11. The blood filter according to claim 9, wherein each of the legs comprises an inner leg portion and an outer leg portion, the outer leg portion located further away from the longitudinal axis than the inner leg portion. 12. The blood filter according to claim 11, wherein the inner leg portion extends at a first angle with respect to the longitudinal axis, and the outer leg portion extends at a second angle with respect to the longitudinal axis greater than the first angle. 13. The blood filter according to claim 12, wherein the second angle comprises about forty-five degrees with respect to the longitudinal axis. 14. The blood filter according to claim 1, wherein the legs and arms comprise an alloy selected from the group consisting of stainless steel, titanium, Nitinol, Elgiloy, and combinations thereof.
