    • PROBLEM TO BE SOLVED: To provide an ischemic stroke device for removal of at least a portion of an obstruction or clot from an obstructed blood vessel for treatment of ischemic stroke.SOLUTION: An ischemic stroke device 10 includes a telescoping support member 20, a first or proximal expandable member 32 connected to the telescoping support member, and a second or distal expandable member 54 connected to the first expandable member. A proximal portion 34 of the first expandable member is attached to a distal end 24 of an outer shaft of the telescoping support member, and a distal end 36 of the first expandable member is attached to a distal portion 40 of an inner core wire of the telescoping support member. A proximal end 58 of the second expandable member is permanently joined to a distal end 28 of the inner core wire 26. The first expandable member is everted to cover the second expandable member that is used to capture an obstruction or clot, prior to pulling the obstruction or clot into a catheter for removal from a patient's vasculature.
    • 要解决的问题:提供用于从阻塞的血管中去除至少一部分阻塞物或凝块以用于治疗缺血性中风的缺血性卒中装置。解决方案:缺血性卒中装置10包括伸缩支撑构件20,第一 或近端可膨胀构件32,以及连接到第一可膨胀构件的第二或远端可扩张构件54。 第一可膨胀构件的近侧部分34附接到伸缩支撑构件的外轴的远端24,并且第一可膨胀构件的远端36附接到内芯线的远端部分40 伸缩支撑构件。 第二可膨胀构件的近端58永久地连接到内芯线26的远端28.第一可膨胀构件被旋转以覆盖用于捕获阻塞物或凝块的第二可膨胀构件, 阻塞或凝块进入导管以从患者的脉管系统中移除。
