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: A filter and methods of use to provide distal protection during a vascular procedure is provided. The filter includes a first spiral shaped support member joined to a second spiral support member to form a crossover and to form a first generally planar support frame and a second generally planar support frame. A tether is on one of the first end or the second end and a capture structure is attached to the first support frame or the second support frame. The capture structure extends in a non-planar fashion relative to the generally planar first or second support frame to which the capture structure is attached. After use to capture debris, the filter is recovered in a manner to close while maintaining captured debris within the filter.
