  • Cryosurgical apparatus
    Patent number: 5224943
    Abstract: A cryosurgical probe for freezing human or animal tissue in a surgical procedure utilising the Joule Thomson effect. The probe is provided with a valve arrangement which enables selective purging and freezing cycles to be employed in rapid succession, and remote from the Joule-Thomson nozzle. In this way purging is limited to those parts of the probe which are affected by moisture contamination during the normal pre-sterilising process, and without interference with the Joule-Thomson nozzle.
