Apparatus (20) and methods are provided for use in filtering emboli from a vessel and/or performing thrombectomy and embolectomy, wherein a vascular device comprises one or more support hoops (24) connected near a distal end (23) of a guide wire, each support hoop (24) having an articulation region, and a blood permeable sac (28) affixed to the support hoop (24) or hoops to form a mouth of the blood permeable sac (28). The mouth of the sac (28) closes when the apparatus (20) is collapsed for removal to prevent material from escaping from the sac (28).
La présente invention concerne un dispositif et un procédé conçus pour éliminer par filtrage les emboles d'un vaisseau et/ou pour exécuter des thrombectomies et embolectomies. On utilise à cet effet un dispositif vasculaire comprenant au moins un cerceau support monté à proximité d'une extrémité distale d'un fil-guide. Chaque cerceau comporte une zone d'articulation. En outre, un sac perméable au sang est monté sur les cerceaux support de façon à former l'embouchure du sac perméable au sang. L'embouchure du sac se referme lorsqu'on replie l'appareil pour retrait, ce qui évite à la matière de s'échapper du sac.
