An elongate distal protection device includes an intraluminal filter-occluder combination positioned at a distal end thereof. An expandable occluder is disposed within an expandable filter such that the filter and occluder are independently deployable. During use, the expanded occluder may be used first to stop embolic particles for aspiration thereof. Then, the occluder may be collapsed, leaving the filter expanded to capture any remaining embolic particles.
