Abstract

A rail stent adapted for use as a vena cava filter having rail members that extend through apertures formed through the wall of the stent support member. The rail members are pre-formed in such a manner such that they bend and overlap at their distal ends to form a filter member and capture particulates or emboli in the blood stream. Removal of the filter is easily accomplished because the rail members slide through the apertures in the stent member during extraction. If tissue has grown around the stent member, it can remain in situ while the filter itself is withdrawn.
