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; 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; and
a 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.

Abstract
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.
