Fig 1 A wire hooked around the filter apex from above. Both ends of the wire exit the left brachial 8Fr sheath. From below, a wire has hooked an inferior strut, with both ends exiting the 11Fr sheath.

Fig 2 A, Gentle retraction was held from above and below to collapse the filter and prevent filter movement. The 8Fr sheath was advanced slowly over the superior barbs. B, The 11Fr sheath was then advanced over the inferior barbs and the 8Fr sheath in an intussusception fashion. The filter and the wires were removed from below.

Fig 3 Distortion caused by sheath and wire combination. Use of a 0.035-inch wire (left) caused the 8Fr sheath to flatten, or “fish mouth.” This flattening effect would not allow filter retrieval. Use of a thinner, 0.014-inch wire (right) did not cause the sheath to flatten.
