摘要： A vascular filter system comprises a vascular filter (1), a clamp device (50), and a delivery catheter (51). The filter (1) comprises filter elements (6). When used without the clamp device (50), the filter elements (6) move from a closed state to an open state upon elapse of a predetermined period of time. In the closed state the filter elements (6) capture thrombus passing through the inferior vena cava (2). The delivery catheter (51) is employed to deliver the clamp device (50) to the filter (1) after the filter (1) has been deployed in the inferior vena cava (2). The clamp device (50) engages with the filter elements (6) of the filter (1) to clamp the filter (1) in the closed state beyond elapse of the predetermined period of time. Because of the presence of the clamp device (50), the filter elements (6) are no longer free to move from the closed state to the open state upon elapse of the predetermined period of time. In this manner the period of time in which the filter (1) captures thrombus is extended either temporarily or permanently.
摘要翻译：血管过滤系统包括血管过滤器（1），夹紧装置（50）和输送导管（51）。过滤器（1）包括过滤元件（6）。当在没有夹紧装置（50）的情况下使用时，过滤元件（6）在经过预定时间段后从关闭状态移动到打开状态。在关闭状态下，过滤元件（6）捕获穿过下腔静脉（2）的血栓。在过滤器（1）已经部署在下腔静脉（2）中之后，输送导管（51）用于将夹紧装置（50）输送到过滤器（1）。夹持装置（50）与过滤器（1）的过滤元件（6）接合，以将过滤器（1）夹紧在超过预定时间段的关闭状态。由于存在夹紧装置（50），所以过滤器元件（6）在经过预定时间段后不再能够自由地从关闭状态移动到打开状态。以这种方式，过滤器（1）捕获血栓的时间段暂时或永久地延长。

摘要： A medical guidewire (1) suitable for advancement through a vasculature comprises a core element (2) extending along the length of the guidewire (1), a first coil (6), and a distal end cap (7). The core element (2) comprises a proximal portion (3), an intermediate portion (4), and a distal portion (5). The distal portion (5) is plastically deformable to facilitate steering of the guidewire (1). The first coil (6) is located radially outwardly of the core element (2). The first coil (6) extends along the distal portion (5) and part of the intermediate portion (4).

摘要： A distal access embolic protection system and methods of using the same for the capture and removal of embolic material from a blood vessel during an interventional procedure are provided. A distal access embolic protection system is inserted through the wall of the blood vessel at a position distal to a stenosis and a distal access filter device is deployed at the point of insertion. After the filter is deployed and is filtering blood that is flowing across the treatment site, an interventional procedure can be performed at the treatment site. After the procedure, the filter device can be collapsed and removed from the blood vessel. A further method is provided wherein a second embolic protection system including a second filter is advanced to the treatment site using a transcatheter technique after the distal access filter has been deployed. A distal access embolic protection system is also provided.
摘要翻译：提供远端通路栓塞保护系统及其使用方法，用于在介入手术过程中从血管捕获和去除栓塞物质。远侧进入栓塞保护系统在远端狭窄位置穿过血管壁插入远端进入过滤装置。在过滤器部署并且正在过滤流经治疗部位的血液之后，可以在治疗部位进行介入手术。在该过程之后，过滤装置可以从血管收缩并移出。提供了一种另外的方法，其中包括第二过滤器的第二栓塞保护系统在远端进入过滤器已部署之后使用经导管技术进行到治疗部位。还提供远端通路栓塞保护系统。

摘要： A medical guidewire (1) suitable for advancement through a vasculature comprises a core element (2), a collar element (3), a distal outer element (4), a proximal outer element (5), and a distal end cap (6). The collar element (3) is fixedly attached to the core element (2) proximally of the distal end of the guidewire (1), and extends radially outwardly from the core element (2). The collar element (3) acts as a stop to limit distal movement of a medical device over the guidewire (1).
