摘要： This is a balloon catheter having at least two lumens. One of the lumens is a large working lumen. The balloon catheter is especially useful as a guide catheter and may be used in a variety of therapeutic and diagnostic procedures. In particular, it has value in treating neurovascular embolic strokes in combination with other devices which are delivered to the stroke site through that working lumen. The remainder of the lumens typically are used to inflate and to deflate the balloon. It is highly preferable that the balloon or inflatable member be situated in a recess in the outer wall of the inventive catheter. Additionally, the distal end of the catheter past the balloon is preferably tapered. The catheter has a very low profile as compared to other catheters of the neurovascular balloon catheter genre. It may include other features such as variable stiffness along the axis of the device and anti-kinking components. The balloon is preferably compliant in nature. When intended for use in treating embolic stroke, the catheter may be a component of a kit including a foreign body retriever. Further, amongst other procedures, the invention includes methods of temporarily blocking a vascular lumen, of removing neurovascular or peripheral emboli. Other procedures, where diagnosis or treatment is needed in a vascular space and a large working lumen is desired, are suitable procedures for the balloon catheter.

摘要翻译： 这是具有至少两个流明的球囊导管。 其中一个流明是一个大的工作流明。 气囊导管特别可用作导向导管，并可用于各种治疗和诊断程序。 特别地，它具有治疗神经血管栓塞中风的价值，与通过该工作腔输送到中风部位的其它装置组合。 其余的腔体通常用于充气并使气囊放气。 高度优选的是，球囊或可膨胀构件位于本发明导管的外壁中的凹部中。 此外，穿过球囊的导管的远端优选是锥形的。 导管与神经血管球囊导管类型的其他导管相比具有非常低的轮廓。 它可以包括其它特征，例如沿设备的轴线的可变刚度和抗扭结部件。 气囊优选地是符合本体的。当用于治疗栓塞性中风时，导管可以是包括异物检查器的试剂盒的组件。 此外，除其他程序之外，本发明包括临时阻塞血管腔，去除神经血管或外周栓塞的方法。 期望在血管空间和大的工作腔中需要诊断或治疗的其它方法是球囊导管的合适程序。
