Abstract
A filter device for temporary placement of a filter in an artery or vein is disclosed. The device includes an expandable filter mounted on a distal end of a catheter. The filter comprises a plurality of circumferentially adjacent porous segments that are arranged generally about the surface of a cone having an open base, and the segments are engaged to one another by means, such as a hook. The filter conforms to the interior of a vessel wall when expanded and contracts to a consistent diameter without bunching when stowed. Methods of using the filter device to entrap and remove embolic material from a vessel during endovascular procedures are also disclosed.
