A device (100) for inferior retrieval of a vena cava filter (120) includes an outer sheath (102) with a first radial window (112) closer to the distal end than the proximal end of the outer catheter； an inner sheath (104) generally extending movably inside the lumen of the outer sheath and having a second radial window (114)； and a snare tool (106) having an elongated guide element extending through the inner sheath and a snare loop (110) distally attached to the guide element. The snare loop is extendable outward through the two radial windows.
