1. A method of manufacture of an intravascular filter device comprising the steps of:
- providing a tube, the tube having an outer diameter and an inner diameter, an axis running through the center of the tube, and a proximal end and a distal end;
cutting slots in the tube extending from the outer diameter to the inner diameter and from the distal end to a point proximate the proximal end, such that the slots create elongate members having a distal region and a proximal region fixedly attached by a ring of tube material at the proximal end of the tube;
shape-setting the elongate members to expand from a first position to a second position, in the second position the elongate members extending generally away from and around the axis of the tube to form a generally circulative mouth; and
disposing a filter material on the distal end.

Abstract
An intravascular filter device comprising a frame having an open configuration and a closed configuration, the frame comprising a plurality of elongate members each having a proximal end and a distal end, and a proximal region and a distal region and being fixedly connected at the proximal end to each other; and a filter having an open end and a closed end disposed on the frame; wherein the elongate members have a bend distal the proximal region and a helical curve over a substantial length of the distal region when the elongate members are in the open configuration.
