摘要:
A device for freezing body tissue, the device having a main driving system capable of generating nitrogen under physical conditions near a critical point of a liquid-vapor system for the nitrogen. The critical point defines a point in a phase diagram of the liquid-vapor system where molar volumes are substantially equivalent for liquid and gas and the physical conditions include a pressure of about 33.5 atm.
