    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: An endoluminal filter including a first support member and a second support member attached to the first support member to form a crossover. A material capture structure extends between the first and second support members, the crossover and the first end or the second end of the first support member. The filter includes at least one tissue anchor on the first support member and the second support member. There is a method of positioning a filter within a lumen including advancing a sheath containing a filter through the lumen. Next, deploying a retrieval feature against the lumen wall while maintaining substantially all of a material capture structure of the filter within the sheath. Next, deploying the material capture structure of the filter from the sheath to a position across the lumen along with engaging the lumen wall with fixation elements positioned along the filter.
