Abstract
A vascular filter includes a proximal support hoop, a plurality of support struts, and a plurality of capture arms. The proximal support hoop extends around the internal wall of the inferior vena cava in a wave pattern having six distal peaks and six proximal peaks. The proximal support hoop includes an enlarged end element at each peak. The support struts extend longitudinally along the internal wall of the inferior vena cava in a curve. Two capture arms are connected to the proximal support hoop at each distal peak. Each capture arm extends from the distal peak to an apex in a curve. The concave portion of the first curve faces inwardly towards the concave portion of the second curve.
