摘要： The method comprises the steps of advancing a guidewire from a first intermediate location to a further intermediate location which is proximal of the treatment location and, subsequently, advancing a medical device over the guidewire toward the further intermediate location. The method may comprise repeating these steps for additional intermediate locations. In one case the treatment location is in the carotid artery. The treatment location may be at or adjacent to the carotid bifurcation. An intermediate location may be at or adjacent to the aortic arch. An intermediate location may be at or adjacent to the carotid take-off. The medical device may be delivered over the guidewire using a delivery catheter. The delivery catheter and the medical device may be advanced through the vasculature without the use of a guide catheter.
摘要翻译：该方法包括以下步骤：将导丝从第一中间位置推进到位于治疗位置附近的另外的中间位置，并且随后将医疗装置推过导丝朝向另外的中间位置。该方法可以包括对于另外的中间位置重复这些步骤。在一种情况下，治疗位置在颈动脉中。治疗位置可以在颈动脉分叉处或其附近。中间位置可以在主动脉弓处或邻近主动脉弓。中间位置可以在颈动脉起搏处或邻近。医疗装置可以使用输送导管在导丝上传送。输送导管和医疗装置可以通过脉管系统而不使用导向导管。

摘要： In a method for filtering embolic material, a guide catheter (5) is advanced through a vasculature. A delivery catheter (4), a guidewire (2) and a collapsed filter are advanced together through the guide catheter (5) to a point distally of the distal end of the guide catheter (5). The guidewire (2) is then advanced across the lesion. During this advancement of the guidewire (2), the delivery catheter (4) and the collapsed filter remain substantially stationary. When the guidewire (2) has crossed the lesion, the delivery catheter (4) and the collapsed filter are then advanced across the lesion until the collapsed filter is distal of the lesion. The delivery catheter (4) is then withdrawn to facilitate deployment of the filter at the location distal of the lesion to ensure that any embolic material released during performance of an interventional procedure at the lesion will be captured and safely retained within the filter.
摘要翻译：在用于过滤栓塞材料的方法中，引导导管（5）通过脉管系统前进。输送导管（4），导丝（2）和塌陷过滤器通过引导导管（5）一起前进到导向导管（5）的远端的远端。导线（2）然后前进穿过病变。在引导线（2）的这种推进过程中，输送导管（4）和塌陷的过滤器保持基本上静止。当导丝（2）穿过病变时，输送导管（4）和塌陷的过滤器然后前进穿过病变，直到塌陷的过滤器处于病变的远端。然后将输送导管（4）取出以便于在病变部位的远端位置处布置过滤器，以确保在损伤处执行介入手术期间释放的任何栓塞物质将被捕获并安全地保持在过滤器内。

摘要： A clot retrieval device (9501) for removing occlusive clot from a blood vessel comprises an inner elongate body (9503) and an outer elongate body (9504) at least partially overlying the inner elongate body (9503). The device also comprises an elongate member or shaft (9502) having a proximal end which extends exterior of a patient so that a user can retrieve the stent-basket device and captured clot by retracting the shaft (9502). The outer elongate body (9504) and the inner elongate body (9503) are connected to the distal end of the shaft (9502) and are expandable relative to the shaft (9502) from a collapsed delivery configuration to an expanded deployed configuration. The outer elongate body (9504) is expandable relative to the inner elongate body (9503) to a radial extent which is greater than the radial extent of the inner body (9503) in the deployed configuration.

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.
