摘要:
A cryoablation system has a gas source which provides a working nitrogen gas at room temperature and at a constant set pressure, a liquid generator which is coupled to the gas source to receive the working gas, and which then generates a working cryogen fluid, and a catheter coupled to the liquid generator for receiving the working cryogen, the catheter having a distal section having a freezing element which delivers the working cryogen to a treatment location, the catheter also having a balloon positioned adjacent the distal section.
摘要(中):
冷冻消融系统具有在室温和恒定设定压力下提供工作氮气的气体源,与气体源连接以接收工作气体并随后产生工作制冷剂流体的液体发生器,以及 连接到液体发生器以接收工作冷冻剂的导管,导管具有远端部分,该远端部分具有将工作冷冻剂输送到治疗位置的冷冻元件,该导管还具有邻近远端部分定位的球囊。
