Abstract

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