    摘要： A device for performing therapeutic or diagnostic procedures within the cerebrovasculature includes a catheter having a distal portion, a proximal portion and a lumen extending therebetween, the catheter including an expandable region for engaging the vessel wall, thrombus, atheroma, or other structures. The device further includes an elongate stretching member, which can be a guidewire, insertable longitudinally through the lumen of the catheter, the elongate stretching member being configured for stretching at least a portion of the catheter and causing the expandable region to transition from an expanded state to a collapsed state, and wherein the elongate stretching member is retracted proximally relative to the catheter causes the expandable region to transition from the radially collapsed state to a radially, or laterally expanded state.

    摘要： Disclosed is a clot and foreign body removal system, including a catheter with at least one lumen. Located within the catheter is a clot capture wire that is connected to a hub at the proximal end. In one embodiment, the clot capture wire includes a coil made out of an elastic or superelastic material, preferably nitinol. The elasticity or superelasticity of the coil allows it to be deformed within the catheter and to then reform its original coil configuration when the coil is moved outside of the catheter lumen. In another embodiment the coil is a biphasic, shape memory coil, which changes shape upon heating, energy application, or passing an electric current. Once the coil configuration has been established, the coil can be used to ensnare and corkscrew a clot or blockage in a vessel. A clot is extracted from the vessel by moving the clot capture coil and catheter proximally until the clot can be removed completely or released into a different vessel that does not perfuse a critical organ. Foreign bodies are similarly captured by deploying the coil distal to the foreign body and moving the clot capture coil proximally until the foreign body is trapped within the coil. By removing the device from the body, the foreign material is also removed.

    摘要翻译： 公开了一种血块和异物去除系统，包括具有至少一个内腔的导管。 位于导管内的是在近端连接到轮毂的血块捕获线。 在一个实施方案中，凝块捕获线包括由弹性或超弹性材料制成的线圈，优选镍钛诺。 线圈的弹性或超弹性允许其在导管内变形，然后当线圈移动到导管腔体外部时改变其原始线圈构型。 在另一个实施例中，线圈是双相形状记忆线圈，其在加热，能量施加或通过电流时改变形状。 一旦建立了线圈配置，线圈就可以用于在容器内锁住和开瓶凝块或堵塞。 通过将凝块捕获线圈和导管向近端移动直到凝块可以完全去除或释放到不灌注关键器官的不同容器中，从血管中提取凝块。 类似地通过将线圈远离外来部署线圈并将血块捕获线圈向近侧移动，直到异物被捕获在线圈内，类似地捕获异物。 通过从体内取出装置，也会去除异物。
