    摘要： A method for the treatment of a stenosis or an occlusion in a blood vessel is disclosed in which a main catheter is first delivered to a site proximal to the occlusion. The main catheter may include an occlusive device at its distal end. An inner catheter or elongate member (e.g., a guidewire) having an occlusive device at its distal end is delivered to the site of the occlusion, and the occlusive device is activated at a site distal to the occlusion. A therapy catheter is then introduced to treat the occlusion. Next, a catheter is delivered just proximal to the occlusive device, and this catheter is used to aspirate and/or irrigate the area removing particles and debris. The aspiration and irrigation steps are preferably repeated until the particles and debris are removed. Perfusion may be performed by using a perfusion-filter distal of the lesion to be treated or a hypotube which extends beyond the occlusive device attached to the guidewire. The present invention provides for a minimally invasive procedure which can be performed quickly and efficiently, with reduced risks to the patient.

    摘要翻译： 公开了一种用于治疗血管狭窄或闭塞的方法，其中主导管首先被输送到接近闭塞的部位。 主导管可以在其远端处包括闭塞装置。 在其远端具有闭塞装置的内导管或细长构件（例如，导丝）被输送到闭塞部位，并且闭塞装置在远端闭塞位置被激活。 然后引入治疗导管以治疗闭塞。 接下来，将导管刚好靠近闭塞装置输送，并且该导管用于抽吸和/或冲洗除去颗粒和碎屑的区域。 优选重复抽吸和冲洗步骤，直到除去颗粒和碎屑。 灌注可以通过使用待治疗的病变的远侧的灌注过滤器或延伸超过连接到导丝线的闭塞装置的海波管来进行。 本发明提供了可以快速有效地执行并降低患者风险的微创手术。
