Beschreibung
Zusammenfassung:	An intravascular expandable filter which has centering members that work to center the filter in a body vessel, the centering member creating a zone at the radial extent of the filter substantially parallel to the longitudinal axis of the filter. A device to deploy the filter consisting of an inner sheath with radially expandable distal arms having slots in them to receive the elongate members of the filter. A device to receive the filter consisting of a member to push a central portion of the filter into a receiving portion of the device. L'invention concerne un filtre expansible intravasculaire qui comprend des éléments de centrage agissant de façon à centrer le filtre dans un vaisseau corporel, l'élément de centrage créant une zone au niveau de la limite radiale du filtre sensiblement parallèle à l'axe longitudinal du filtre. L'invention concerne également un dispositif qui permet de déployer le filtre et qui consiste en une gaine intérieure comprenant des bras distaux radialement expansibles munis de fentes permettant de recevoir les éléments allongés du filtre. L'invention concerne enfin un dispositif qui est conçu pour recevoir le filtre et qui consiste en un élément servant à pousser une partie centrale du filtre dans un partie de réception du dispositif.
