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.

Abstract: A method of manufacturing an elongate shaft for delivery of a medical device may include disposing a polymeric sheath having a lumen extending therethrough over a mandrel; sliding a proximal portion of the polymeric sheath into a lumen of a metallic tubular member; placing a polymeric tubular member over the distal portion of the polymeric sheath and a distal portion of the metallic tubular member; fixedly attaching a proximal coupler to a distal end of a longitudinal support filament; inserting a proximal end of the longitudinal support filament between the polymeric sheath and the polymeric tubular member to position the longitudinal support filament alongside the distal portion of the metallic tubular member and a distal portion of the polymeric sheath; and reflowing the polymeric tubular member to secure the longitudinal support filament relative to the polymeric sheath and the metallic tubular member.
