摘要： A fluid purging system has a spring-energized relief valve having an inlet port that is coupled to a fluid chamber to receive incoming fluid, and an outlet port through which incoming fluid is relieved. The outlet port is fluidly coupled to a pressurized chamber. The fluid purging system also includes an electro-mechanical pressure switch, and an electrically operated solenoid valve which functions as a pressure exhaust valve. The pressure switch and the solenoid valve are in fluid communication with the pressurized chamber.

摘要： A cryoablation system has a gas source which provides a working gas at room temperature and at a constant set pressure. The system also includes a liquid generator which is coupled to the gas source to receive the working gas, and which then generates a working cryogen fluid in a liquid phase that operates at a temperature and pressure that lies on its Joule-Thomson Inversion Curve, with the Joule-Thomson coefficient maintained within the range 0.00±0.08 degrees F./Atmosphere. The system also includes a catheter coupled to the liquid generator for receiving the working cryogen, the catheter having a distal section which delivers the working cryogen to a treatment location.
