Abstract: An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may directly cool tissue contacting the balloon (212), or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter.Plural balloons may be provided, wherein a secondary outer balloon (212) surrounds a primary inner balloon (203), the primary balloon being filled with coolant and acting as the cooling chamber. The secondary balloon is coupled to a vacuum return lumen (205) to serve as a robust leak containment device and thermal insulator around the cooling chamber.

Abstract: An elongated catheter device with a distal balloon assembly is adapted for endovascular insertion. Coolant injected through the device may, in different embodiments, directly cool tissue contacting the balloon, or may cool a separate internal chamber. In the first case, the coolant also inflates the balloon, and spent coolant is returned to the handle via a return passage extending through the body of the catheter.Plural balloons may be provided, wherein a secondary outer balloon surrounds a primary inner balloon, the primary balloon being filled with coolant and acting as the cooling chamber, the secondary balloon being coupled to a vacuum return lumen to serve as a robust leak containment device and thermal insulator around the cooling chamber. Various configurations, such as surface modification of the balloon interface, or placement of particles, coatings, or expandable meshes or coils in the balloon interface, may be employed to achieve this function.
Abstract translation: 具有远端球囊组件的细长导管装置适于血管内插入。 在不同的实施例中,通过装置注入的冷却剂可以直接冷却接触气囊的组织,或者可以冷却单独的内部室。 在第一种情况下,冷却剂还使气囊膨胀,并且废弃的冷却剂经由延伸穿过导管主体的返回通道返回到手柄。可以提供柔性气囊,其中次级外气囊围绕主内气球, 初级球囊充满冷却剂并充当冷却室,次级气球与真空回流腔相连,用作强制性的泄漏容纳装置和围绕冷却室的绝热体。 可以采用各种构造,例如球囊界面的表面改性,或者在气球界面中放置颗粒,涂层或可膨胀的网孔或线圈,以实现该功能。
