1. 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; and
a probe receptacle configured to receive a needle probe, wherein the probe receptacle is configured to couple the needle probe to the cryogen cartridge via the cryogen pathway, and wherein the needle probe comprises:
one or more needles each having a needle lumen disposed therein;
a first sealing element at a proximal side of a first location;
a second sealing element at a distal side of the first location;
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 extension extending proximally, the probe extension having a probe lumen disposed therein, the probe lumen including an elongate element that extends from a proximal end to a distal end, wherein the probe lumen is coupled to:
the needle lumens at the distal end, and
an inlet of the cryogen pathway at the first location in between the proximal end and the distal end so as to reduce an outward force on the needle probe,
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.
