    • A vascular graft (30) comprises a proximal inlet section (31), a first distal section (32) and a second distal section (33). The first distal section (32) and the second distal section (33) are attached to the proximal inlet section (31) at a Y-shaped bifurcation region. In use the proximal inlet section (31) is attached to a first part (34) of a host artery in an end-to-side anastomosis. A second part (35) of the host artery is cut to form a first section (36) of the host artery on a first side of the cut and a second section (37) of the host artery on a second side of the cut. The first distal section (32) is attached to the first section (36) in an end-to-end anastomosis, and the second distal section (33) is attached to the second section (37) in an end-to-end anastomosis. When implanted the graft (30) directs blood flow from the first part (34) of the host artery through the proximal inlet section (31), into the second distal section (33) and into the second section (37) of the host artery along a single flow path.
    • 血管移植物(30)包括近端入口部分(31),第一远端部分(32)和第二远端部分(33)。 第一远端部分(32)和第二远端部分(33)在Y形分叉区域附接到近侧入口部分(31)。 在使用中,近端入口部分(31)以端对侧吻合方式连接到宿主动脉的第一部分(34)。 主动脉的第二部分(35)被切割以在切口的第一侧上形成主动脉的第一部分(36)和在切口的第二侧上的主动脉的第二部分(37)。 第一远端部分(32)以端对端吻合方式附接到第一部分(36),并且第二远端部分(33)以端对端吻合方式附接到第二部分(37) 。 当移植物(30)植入时,将来自主动脉的第一部分(34)的血液通过近侧入口部分(31)引导到第二远端部分(33)中并进入主动脉的第二部分(37) 沿着单个流动路径。

    • A vascular graft comprising a proximal section, iliac distal legs and a bifurcation blending section (7) between the proximal section and the distal legs. The cross-sectional area of the proximal section at the bifurcation point is less than or equal to the sum of the two cross sectional areas of both iliac legs. The blending section (7) generates a smooth transition from the proximal section to both iliac legs which minimizes wave reflections by ensuring that the area ratio at the bifurcated junction (7) is as close to unity or greater than unity as possible. The blending section (7) defines a first lumen for fluid flow from the proximal section into the first distal leg, and a separate second lumen for fluid flow from the proximal section into the second distal leg. The two lumen are separated by means of a gradual flow which separates the fluid flow from the proximal section into each lumen. The distal legs are connected to the blending section (7) at the bifurcation region to form a substantially “Y”-shaped graft.
    • 一种血管移植物,包括近端部分,髂骨远端腿部和近端部分和远端腿部之间的分叉混合部分(7)。 在分叉点处的近端部分的横截面面积小于或等于两个髂腿的两个横截面面积的总和。 混合部分(7)产生从近端部分到两个髂骨腿的平滑过渡,其通过确保分叉连接点(7)处的面积比尽可能接近于一致或大于单位而使波反射最小化。 混合部分(7)限定用于从近端部分进入第一远端腿部的流体流动的第一腔,以及用于从近端部分流入第二远端腿部的流体的单独的第二腔。 通过将流体从近端部分分离成每个管腔的逐渐流动来分离两个内腔。 远端腿在分叉区域连接到混合部分(7)以形成基本上“Y”形的移植物。

    • A vascular filter device (1) has a perfusion balloon (3) with a through-hole for blood flow. There is a distal filter (4) for trapping emboli, and the filter (4) is configured to filter an annular cross-sectional area extending from a vessel wall, while leaving an un-filtered central passageway. The filter (4) may be substantially frusto-conical in shape when deployed, and have a proximal tubular part (41) which is attached to the perfusion balloon or a support for the perfusion balloon. The filter has a retainer (5) to retain an end of the filter in an in-use position abutting a vessel wall. The retainer may comprise wires (5) or an inflated ring (8). The device may have an internal support (2, 12, 22, 96, 112) for the perfusion balloon (3, 11, 21, 95, 111). The balloon inflates and expands the inner arterial wall, and the filter captures emboli released during the procedure while leaving a channel that allows blood to flow to tissues distal to the blockage, maintaining antegrade flow. This may prevent the onset of an ischemic stroke or other perioperative neurological events.
    • 血管过滤器装置(1)具有带有用于血流的通孔的灌注球囊(3)。 存在用于捕获栓塞的远端过滤器(4),并且过滤器(4)构造成过滤从容器壁延伸的环形横截面区域,同时留下未过滤的中心通道。 过滤器(4)在展开时可以基本上为截头圆锥形,并且具有附接到灌注球囊的近端管状部分(41)或用于灌注球囊的支撑件。 过滤器具有保持器(5),以将过滤器的端部保持在与容器壁相邻的使用中的位置。 保持器可以包括电线(5)或充气环(8)。 该装置可以具有用于灌注球囊(3,11,21,91,111)的内部支撑件(2,12,22,96,112)。 气囊膨胀并膨胀内动脉壁,并且过滤器捕获在手术期间释放的栓塞,同时留下允许血液流动到远离阻塞的组织的通道,保持顺行流动。 这可能会阻止缺血性卒中或其他围手术期神经系统事件的发生。
