ABSTRACT:
A collapsible filter element (40) for a transcatheter embolic protection device (1). The filter element (40) comprises a collapsible filter body (41) which is movable between a collapsed stored position for movement through a vascular system and an expanded position for extension across a blood vessel such that blood passing through the blood vessel is delivered through the filter element (40). A proximal inlet portion of the filter body (41) has two inlet openings (50) sized to allow blood and embolic material enter the filter body (41), and a distal outlet portion of the filter body (41) has a plurality of small outlet openings (51) to allow through-passage of blood, but to retain embolic material within the filter body (41). The filter body (41) is of an oriented polymeric material.
