Abstract
Filtering device useful for partly interrupting the inferior vena cava and for creating an efficient barrier against embolic migration; in the expanded operating condition, said device comprises a filiform body, extended at one of its ends by a plurality of diverging flexible wires, which wires are regularly circumferentially spaced apart one with respect to the other, while the free end of each one is bent outwardly to form a fastening tip, the other end of said body ending in a stabilizer which also acts as a second filter, constituted of a plurality of flexible wires, diverging around said body, which wires are regularly circumferentially spaced one with respect to the other and are offset of a certain angle with respect to the wires constituting the first filter.
