Claim 14:
15. A cryogenic device comprising:
a cartridge holder for holding a cryogen cartridge comprising a cryogen, wherein the cryogen cartridge is coupleable to a cryogen pathway;
a probe receptacle configured to receive a probe extension of a needle probe, the probe extension having a proximal end and a distal end, wherein the probe receptacle is configured to receive the proximal end of the probe extension, and wherein the probe receptacle comprises:
a first sealing element and a second sealing element for sealing the probe receptacle;
a supply valve between the cryogen cartridge and the second sealing element, the supply valve configured to transition from an open position to a closed position; and
a probe receptacle configured to, when the probe extension is secured to the probe receptacle, couple a lumen of the probe extension to an inlet of the cryogen pathway and introduce the cryogen into the lumen of the probe extension, wherein the probe receptacle couples to the inlet of the cryogen pathway at a first location between the proximal end and the distal end of the probe extension, wherein the first location is disposed between the first sealing element and the second sealing element,
wherein the first sealing element and the second sealing element seal the proximal end and the distal end of the probe receptacle from venting to ambient air when the supply valve is in the open position and when the supply valve is in the closed position, and wherein the first sealing element and the second sealing element do not translate with the supply valve in the open position and the closed position so as to stabilize pressure within the probe receptacle.
