摘要： An embolic protection device comprises a collapsible filter element for delivery through a vascular system of a patient. The filter element comprising a collapsible filter body and a filter support frame contacting the filter body. The collapsible filter body has an inlet end and an outlet end, the inlet end of the filter body having one or more inlet openings sized to allow blood and embolic material to enter the filter body, the outlet end of the filter body having a plurality of outlet openings sized to allow through passage of blood but to retain undesired embolic material within the filter body. The filter support frame is movable between a collapsed position for movement through the vascular system and an extended outwardly projecting position to support the filter body in the expanded position. The frame has a plurality of engagement segments which are spaced-apart longitudinally and transversely when the filter body is in the deployed expanded configuration to urge the filter body into opposition with the vessel wall. The engagement segments define at least partially a substantially helical engagement track.

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 delivery and deployment system for a self-expanding stent comprises a proximal handle having a rotatable thumbscrew and a sliding component which is attached to a distal stent restraining sheath. A rigid open coil spring is provided for converting rotation of the thumbscrew into translation of the sliding component). The spring is attached to the thumbscrew. The sliding component is located between adjacent coils of the spring. Rotation of the thumbscrew twists the spring and slowly slides the sliding component and hence the distal sheath in the proximal direction to uncover the stent, removing the constraint on the stent which is accurately deployed at the site of interest. The handle has a guide elongate channel which constrains the sliding component so that it cannot move in a rotational direction.

摘要： A vascular filter device (1) comprises a plurality of filter elements (6) which are movable from a capturing position to an open position upon elapse of a predetermined period of time. In the capturing position the filter elements (6) are configured to capture thrombus passing through the inferior vena cava. In the open position the filter elements (6) are configured to facilitate unrestricted blood flow. The filter elements (6) are biased towards the open position. The filter (1) comprises a holder member (10) to temporarily hold the filter elements (6) in the capturing position until elapse of the predetermined period of time. The holder member (10) comprises a biostable wire element (12) which extends through an opening (13) in each filter element (6), and a biodegradable/bioabsorbable stop element (11). Upon biodegrading/bioabsorbing of the stop element (11), the filter elements (6) are free to move from the capturing position to the open position.
