Abstract: In an embodiment, a method for detecting leaks in a shaft of a cryoablation system includes placing a vacuum pump in fluid communication with a return tube and a supply tube; pulling a vacuum within the supply tube and the return tube; after pulling the vacuum for a predetermined amount of time, measuring a vacuum pressure within the supply tube and the return tube; and analysis of the vacuum pressure to assist with identifying leaks in the system.

Abstract: In an embodiment, a cryoablation system includes a pre-cooler gas circuit, a working gas circuit isolated from the pre-cooler gas circuit, and a vacuum chamber isolated from the pre-cooler gas circuit and the working gas circuit. The cryoablation system can include a shaft having an insulated zone and a working gas expansion chamber distal to the insulated zone. The cryoablation system can further include a handle and a shaft-handle connector, wherein a proximal end of the shaft connects to the shaft-handle connector, wherein the shaft-handle connector is configured to removably attach the proximal end of the shaft to a distal end of the handle.
