Title
(EN) FILTERING DEVICE AND METHOD FOR A VENOUS FURCATION
(FR) DISPOSITIF ET PROCEDE DE FILTRAGE POUR UNE BIFURCATION VEINEUSE
Abstract
(EN) Implantable blood filtering device (20) and method for filtering embolic material (circles) from blood flowing from at least one of source veins (62) and (68) into the sink vein (64) of a venous furcation (60). Device (20) is an expansible, tubular shaped porous mesh-like element (22) of filaments (24), having first end region (e1) positional in a first source vein of venous furcation (60), second end region (e2) positional in a second source vein or in sink vein (64) of venous furcation (60), and middle filtering zone (F) circumferentially and longitudinally extending between first (e1) and second (e2) end regions, whereby middle filtering zone (F) of element (22) when so positioned in venous furcation (60), filters embolic material from blood passing through pores (26) of middle filtering zone (F), while substantially not disturbing flow of blood through venous furcation (60), thereby preventing embolic material from entering sink vein (64) of venous furcation (60).
(FR) La présente invention concerne un dispositif de filtre sanguin (20) et un procédé de filtrage de substances emboliques en provenance du sang s'écoulant à partir d'au moins des veines sources (62) et (68) vers des veines réceptrices (64) d'une bifurcation veineuse (60). Le dispositif (20) consiste en un élément (22) de filaments (24) de type maillage poreux de forme tubulaire et expansible, comprenant une première région d'extrémité (e1) apte à être positionnée dans une première veine source de bifurcation veineuse (60), une deuxième région d'extrémité (e2) apte à être positionnée dans une deuxième veine source ou dans la veine réceptrice (64) de bifurcation veineuse (60), et une zone médiane de filtrage (F) s'étendant en circonférence et en longueur entre les première (e1) et deuxième (e2) régions d'extrémité, grâce à quoi la zone médiane de filtrage (F) de l'élément (22) lorsqu'il est ainsi positionné dans la bifurcation veineuse (60) effectue le filtrage de substance embolique à partir du sang à travers les pores de la zone médiane de filtrage (F) tout en n'entravant pas la circulation de sang à travers la bifurcation veineuse (60), empêchant ainsi la substance embolique de pénétrer dans la veine réceptrice (64) de la bifurcation veineuse (60).
