    摘要： A cryogenic catheter includes an elongate, contiguous, thermally-transmissive region coupled to the catheter, the thermally-transmissive region being sufficiently flexible to change from a linear configuration to an arcuate configuration. The thermally-transmissive region may include a plurality of interconnected thermally-transmissive segments that are generally cylindrical in shape. The cryogenic catheter may be in fluid communication with a fluid source, and may include one or more fluid injection tubes. Further, an injection tube may be slidably disposed within the catheter so that the injection tube is longitudinally movable relative to an outer surface of the catheter. The cryogenic catheter may also be in communication with a controller programmed to regulate delivery of a cryogenic fluid from the fluid source to the medical device.

    摘要翻译： 低温导管包括连接到导管的细长的邻接的热传导区域，该热传导区域具有足够的柔性以从线性构型改变为弧形构型。 该热传导区域可以包括大致圆柱形的多个相互连接的热传递段。 低温导管可以与流体源流体连通，并且可以包括一个或多个流体注入管。 此外，注射管可以可滑动地设置在导管内，使得注射管相对于导管的外表面可纵向移动。 低温导管还可以与被编程为调节低温流体从流体源到医疗装置的输送的控制器连通。
