    • Devices and methods for cooling microwave antennas are disclosed herein. The cooling systems can be used with various types of microwave antennas. One variation generally comprises a handle portion with an elongate outer jacket extending from the handle portion. A microwave antenna is positioned within the handle and outer jacket such that cooling fluid pumped into the handle comes into contact directly along a portion of the length, or a majority of the length, or the entire length of the antenna to allow for direct convective cooling. Other variations include cooling sheaths which form defined cooling channels around a portion of the antenna. Yet another variation includes passively-cooled systems which utilize expandable balloons to urge tissue away from the surface of the microwave antenna as well as cooling sheaths which are cooled through endothermic chemical reactions. Furthermore, the microwave antennas themselves can have cooling lumens integrated directly therethrough.
    • 本文公开了用于冷却微波天线的装置和方法。 冷却系统可用于各种类型的微波天线。 一个变型通常包括具有从手柄部分延伸的细长外护套的手柄部分。 微波天线位于手柄和外护套内,使得泵送到手柄中的冷却液体沿着长度的一部分,或长度的大部分或天线的整个长度直接接触以允许直接对流冷却 。 其他变型包括在天线的一部分周围形成限定的冷却通道的冷却护套。 另一个变型包括被动冷却的系统,其利用可膨胀的气囊来促使组织远离微波天线的表面,以及通过吸热化学反应冷却的冷却鞘。 此外,微波天线本身可以具有直接集成在其中的冷却管道。
