Zusammenfassung: | A filter assembly and methods of using the filter assembly are disclosed. The filter assembly includes a proximal portion including support members and a distal portion including a mesh. The filter assembly may also include additional portions including additional meshes or support members. The proximal portion of the filter has a first major diameter, and the distal portion of the filter has a second major diameter. In a first unconstrained state, the second major diameter of the filter is less than the first major diameter of the filter. According to certain aspects of the disclosure, the filter assembly further includes a filter wire and a tubular member that may be attached to a proximal or distal end of the filter.
L'invention concerne un ensemble de filtre et des procédés d'utilisation de l'ensemble de filtre. L'ensemble de filtre comprend une portion proximale comprenant des éléments de support et une portion distale comprenant une maille. L'ensemble de filtre peut également comprendre des portions supplémentaires comportant des éléments de support ou mailles supplémentaires. La portion proximale du filtre a un premier diamètre principal et la portion distale du filtre a un second diamètre principal. Dans un premier état non contraint, le second diamètre principal du filtre est inférieur au premier diamètre principal du filtre. Selon certains aspects de l'invention, l'ensemble de filtre comprend en outre un fil de filtre et un élément tubulaire qui peut être fixé à une extrémité proximale ou distale du filtre. |
