Abstract

A free standing filter (40) is provided with a filter body (48) having an elongate guide wire receiving member (50) extending centrally therethrough to define an open-ended channel configured to receive a plurality of different sized guide wires. An expandable, and contractible frame (44) surrounds the elongate guide wire receiving member (50), which is connected at a proximal end to the elongate guide wire receiving member. A porous embolic capturing unit (42) has an open-end connected to the frame (44), and a closed end connected to the elongate guide wire receiving member (60) which extends through the porous embolic capturing unit (42).
