Abstract:
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.
