ABSTRACT:
An embolic protection filter having an inverted membrane with improved blood perfusion characteristics is disclosed. An embolic protection filter in accordance with the present invention comprises a filter frame disposable about a guidewire, a support hoop coupled to a plurality of expandable struts, and an inverted membrane for filtering embolic debris. The inverted membrane has a tapered proximal section and an enlarged diameter distal section. Features of the present invention permit the perfusion of blood through the filter irrespective of embolic debris entrained therein.
