Abstract
A filter device assembly and a method of using such a device to capture and remove embolic material from a body lumen or blood vessel are provided. The filter device assembly generally includes a structure having a collapsed state and an expanded state with first, second, and optionally N additional filter members circumferentially attached thereto. Each filter member forms an annulus chamber with the first filter member having porosity P; the second filter member circumferentially having porosity P; and the N additional filter members each having porosity [P. . . P]. The magnitude of the porosity for the first, second, and N additional filter members follows the relationship P>[P> . . . >P]>P. The first, second, and N additional filter portions are configured in the expanded state to allow blood to flow there through and to capture emboli in the annulus chambers.
