Abstract: 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.

Abstract translation: 血管过滤装置（1）具有带有用于血流的通孔的灌注球囊（3）。 存在用于捕获栓子的远端过滤器（4），并且过滤器（4）构造成过滤从血管壁延伸的环形横截面区域，同时留下未过滤的中央通道。 过滤器（4）在展开时可以基本为截头圆锥形，并且具有附接到灌注球囊或灌注球囊的支撑件的近端管状部分（41）。 过滤器具有保持器（5），以将过滤器的一端保持在邻接血管壁的使用位置中。 保持器可以包括线（5）或充气环（8）。 该装置可具有用于灌注球囊（3,11,21,95,111）的内部支撑件（2,12,22,96,112）。 球囊膨胀并扩张动脉内壁，过滤器捕获手术过程中释放的栓子，同时留下一条通道，使血液流向阻塞远端的组织，维持顺行流动。 这可以防止缺血性中风或其他围手术期神经事件的发生。
