Abstract

See full text

A method and system for continuously delivering cryotreatment to a treatment device. In one embodiment, the system may include a first PID circuit in the fluid delivery line and a second PID circuit in the fluid return line, and the first and second PID circuits may operate simultaneously to continuously provide coolant to a cryotreatment device during the inflation phase, ablation phase, and warming (or thawing) phase while providing for temperature adjustment. Alternatively, the system may include a bypass line by which coolant may bypass the subcooler system and be delivered to the cryotreatment device at non-ablation temperatures during the inflation phase. During the ablation phase, coolant may flow through the subcooler system.
