Abstract: An implantable permanent filter assembly (1) for deployment in a bifurcated vessel includes a main vessel and at least two branches. This assembly includes a filtering sleeve (2) formed of an expendable braided framework (20) able to expand from a radially compressed state in a delivery configuration to a radially expanded state. The filtering sleeve extends along an axis and defines a cylindrical lumen devoid of impermeable layer, having a distal end configured to extend toward the branches of the bifurcated vessel and a proximal end configured to extend toward away from the branches of the bifurcated vessel. The braided framework has a plurality of mesh layers (22,23,24) of wires (25) made of biocompatible material, forming a lattice with a plurality of wires of each layers. The lattice, when observed normal with respect to a wall of the implantable endoluminal prosthesis, defines polygonal openings.
Abstract: The present invention relates to implantable endoluminal prosthesis for preventing stroke. The endoluminal prosthesis (1) consists of a braided framework (20) defining a cylindrical lumen (21) devoid of impermeable membrane. Said braided framework (20) is self-expandable comprising a plurality of layers (22, 23, 24) of wires (25) made of biocompatible material. Each layer forms a mesh. The meshes form a lattice with a plurality of wires (2) of given layers (22, 23, 24). The lattice defines polygonal opening units (26) when observed normal to a wall of the implantable endoluminal prosthesis (1). The diameter (Ø25) of wire (25) being at least 30 ?m and at most 150 ?m, the mean diameter (Ø27) of the inscribed circle (27) of the polygonal opening units (26) being at least 75 ?m and at most 200 ?m in fully expanded state. The braided framework (20) consists of at least 128 and at most 512 wires (25).
