    • An implantable permanent filter assembly (1) for deployment in a bifurcated vessel comprises a main vessel and at least two branches. This assembly comprises 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 layers (22,23,24) of wires (25) made of biocompatible material, each layer forming a mesh, the meshes 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, the diameter of the wire being at least 20 micrometres and at most 100 micrometres.

    • The invention relates to a compressible, self-expandable stent for splinting and/or keeping open a cavity, an organ duct, and/or a vessel in the human or animal body. The stent is configured in a tubular fashion and has a mesh of at least one wire (14). At a distal end of the stent, a portion each of the wire is bent into a loop (7), wherein the portion of the wire is wrapped around to form a twist (8) by means of which the loop is closed. The stent has a distal portion, a proximal portion and a transition portion between them, the distal portion being flared to a larger extent than the proximal portion, and the portions comprising a mesh, the region of the proximal portion adjacent to the transition portion in the proximal direction having a decoupling region in which at least two portions each of the at least one wire or of the wires are twisted with each other.

    • A blood filter device having occlusion-resistant characteristics. The occlusion-resistant characteristics decrease the likelihood of the filter being blocked by thrombi. The filter device (252a, 252b) includes at least one anchor portion (42) for anchoring the filter device within one or more arteries (354a, 354b), and a filter portion (98) for filtering thrombi from the blood entering the artery. In some embodiments, an anchor portion is capped with a filter cap. In various embodiments, the filter cap is protrudes into the aorta to promote occlusion resistance. In one embodiment, the device can be modified in situ to re-establish normal blood flow through the artery in the unlikely case of thrombotic or other blockage of the filter. In some embodiments, a bypass opening or open channel defining an access port is provided to accommodate passage of surgical instruments into the artery and to enable blood flow to bypass the filter should the filter become heavily occluded.
    • 具有阻塞特性的血液过滤装置。 阻塞特性降低过滤器被血栓堵塞的可能性。 过滤器装置(252a,252b)包括用于将过滤装置固定在一个或多个动脉(354a,354b)内的至少一个锚固部分(42)和用于过滤血液从进入动脉的血液中过滤部分(98)。 在一些实施例中,锚固部分用过滤器帽盖住。 在各种实施例中,过滤器盖突出到主动脉中以促进阻塞阻力。 在一个实施例中,可以在不太可能发生血栓形成或其他阻塞过滤器的情况下,原位修改装置以重新建立通过动脉的正常血流。 在一些实施例中,设置限定出入口的旁路开口或开口通道,以适应手术器械进入动脉的通道,并且如果过滤器变得严重堵塞,则能使血液流过旁路过滤器。
