Abstract

A cryogenic device with a cartridge holder for a cryogen cartridge, cryogen cartridge is coupleable to a cryogen pathway; a probe receptacle for receiving 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 having needle lumens disposed therein; 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 the cryogen pathway at a first location in between the proximal end and the distal end. Various connection mechanisms for securing needle probes to a handpiece portion are disclosed.
