摘要：
This invention is a surgical device. In particular, it is low profile, single lumen catheter 130 preferably having a movable seal 140 or seat that allows the balloon 138 to be inflated by sealing against the movable guidewire 160 or against itself. An additional variation of the invention includes a non-removable guidewire 160 situated in the catheter body 130 in such a way to provide or add stiffness to the otherwise flexible distal section of the catheter 130 during a procedure. An enhanced strain relief transition joint between significantly stiffer proximal section 136 and the more flexible distal section 132 is provided. Finally, methods of using the inventive balloon catheter are also shown. The balloon 406 is preferably produced of one or more materials that are resistant to components of chemical vaso-occclusive compositions 414 or are resistant to adherence to those compositions.
摘要（中）：
本发明是一种手术装置。 特别地，它是薄型单腔导管130，优选地具有可移动密封件140或座，其允许球囊138通过密封抵靠可动导丝160或与其自身而膨胀。 本发明的另外的变型包括位于导管主体130中的不可移除的导丝160，以在过程期间向导管130的另外柔性的远侧部分提供或增加刚度。 提供了在较硬的近端部分136和更柔性的远端部分132之间的增强的应变消除过渡接头。 最后，还示出了使用本发明的气囊导管的方法。 球囊406优选地由一种或多种对化学血管闭塞组合物414的组分有抗性或对这些组合物的粘附性有抗性的材料制成。
