1. An intravascular filler device for placement on an elongate shaft having a longitudinal axis, the 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, the proximal ends of the elongate members disposed around the elongate shaft and being fixedly connected at the proximal end to each other around the elongate shaft; and
a filter having an open end and a closed end disposed on the frame;
wherein the plurality of elongate members are configured such that the proximal region of the elongate members extends along the longitudinal axis of the elongate shaft;
wherein the elongate members have a first bend at a location intermediate the proximal region and the distal region, and a helical curve distal of the first bend and extending over a substantial length of the distal region when the elongate members are in the open configuration;
wherein through the first bend of the plurality of elongate members the plurality of elongate members extend laterally outward from the longitudinal axis of the elongate shaft.

21. An intravascular filter device having a collapsed configuration and an expanded configuration, comprising:
-
an elongate member; a filter having an inlet lumen and a filter wall, the filter disposed on the elongate member; a plurality of struts, each strut having a first portion and a second portion, wherein, in the expanded configuration, the first portions radiate outwards from the elongate member, and the second portions support the filter inlet lumen and extend in a circumferential direction. - View Dependent Claims (22, 23, 24, 25, 26, 27)
