Design of the filter :

The filter is cone-shaped. Its two levels of anchorage and centering are distinguished by the length of the strands.

The upper level provides an active anchorage. It consists of the shorter strands, showing six legs whose distal extremities are curved in hooks.

The lower level consists of three legs providing the centering. These legs have a concave curvilinear shape reducing the traumatic risk.

These legs are all from unequal length, avoiding the intertwining inside the catheter (introduction sheath).
