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.
Claims29
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.
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, 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;
- and
- disposing a filter material on the distal end.
