    摘要: There is described an endoluminal filter having an end cap having a lumen sized to receive there through a guidewire used in the positioning of the filter within the vasculature. There is a first support member with a pre-formed counter clockwise spiral shape and a second support member with a pre-formed clockwise spiral shape positioned adjacent to one another to form a proximal support frame, a distal support frame with a crossover between the proximal support frame and the distal support frame with a proximal portion of the first and the second spiral support members being attached to the end cap. A material capture structure having a rim and an apex with the rim attached to the proximal support frame and the apex extending distally through without attaching to the distal support frame.

    摘要: In one embodiment of the present invention there is provided a method of filtering blood flow in a lumen by positioning an open loop filter support structure within a lumen; maintaining a position of the open loop filter support structure within the lumen using radial force generated by the open loop filter support structure; and filtering blood flow in the lumen using a filter supported by the open loop filter support structure. In one aspect, there is also applying radial force generated by the open loop filter support structure along the axial dimension of the lumen. In another embodiment of the present invention there is provided a method of providing a filter across a lumen flow path by providing a filter support structure having a first end, a crossover section, and a second end; and fixing the position of the filter support structure within the lumen by positioning the first end against a first portion of the lumen and positioning the second end against a second portion of the lumen; and using the filter support structure to provide a filter across the lumen flow path. In one aspect, the ends do not pierce the lumen surface.

    摘要: In one embodiment of the present invention there is provided a method of providing protection during a procedure performed in the vasculature using an open loop filter device comprising two elongate support members positioned to form at least one crossover location between adjacent open loops of the device. The method may also include placing the open loop device down stream of a location in the vasculature performing a procedure to treat the vasculature in proximity to the location; and capturing debris released during the procedure in a material capture structure suspended between the elongate support members and across the vessel. Additionally, there can be a step of maintaining the open loop filter device downstream of the location along the wall of the vasculature while permitting movement along the wall of the vasculature of the two elongate support members adjacent the material capture structure.
