    摘要： A filter comprising a porous material is arranged in a generally conical shape having an expandable base and a vertex. A reservoir tip is located at the vertex for collecting filtered embolic material. The tip communicates with a distal port and lumen of an aspiration tube for removing embolic material under vacuum. A vessel occluding device comprising a non-permeable material having an expandable conical shape and communicating with an aspiration tube is also disclosed. Methods of using the filter and occluding devices for protecting a patient from embolization during cardiovascular procedures are described.

    摘要： A medical device for filtering embolic material. The device comprises a cannula having a lumen, the lumen communicating with a port at the distal end. A port is located on an outer surface of the cannula adjacent a distal region of the cannula, the port having a passage extending distally and communicating with a distal opening in the port. A filter is removably insertable through the passage of the port, the filter comprising a flexible tubular member, a flexible shaft extending through the tubular member, and an expansion frame mounted on the distal end of the shaft. A filter mesh attached to the expansion frame. The expansion frame may optionally include a cantilever beam to support the far end of the frame, and in certain cases the cantilever beam is flexible to avoid scraping the vessel wall during use. Methods of use are also described.

    摘要翻译： 一种用于过滤栓塞物质的医疗设备。 该装置包括具有内腔的套管，所述内腔与远端的端口连通。 端口位于套管的外部表面上，邻近套管的远侧区域，该端口具有向远端延伸并与端口中的远端开口连通的通道。 过滤器可移除地通过端口的通道插入，过滤器包括柔性管状构件，延伸穿过管状构件的柔性轴和安装在轴的远端上的膨胀框架。 连接到扩展框架的滤网。 扩展框架可以可选地包括支撑框架的远端的悬臂梁，并且在某些情况下，悬臂梁是柔性的，以避免在使用过程中刮擦容器壁。 还描述了使用方法。

    摘要： An endoluminal device having an elongate tubular member and a filter slideably received within a lumen of the tubular member. An obturator tip is carried by the filter and shaped to rest against the distal end of the elongate tubular member when the filter is within the lumen of the tubular member. Methods of using the obturator and the introducer for introducing the filter into a vessel, such as an aorta, are also disclosed.
