  • Patent number: 5324286
    Abstract: A cryogenic apparatus comprises a coolant system and a probe having a cryogenically-cooled cold-tip. The probe is formed of an elongated housing having a distal end closed by the cold-tip and a proximal end connected to the coolant system. The housing is adapted to receive cryogenic droplets entrained in a warm carrier gas stream supplied by the coolant system. The carrier gas stream passes through the housing such that the entrained cryogenic droplets are transported to the distal end of the probe for cooling the cold-tip.
