A cryoablation catheter includes an inner lumen and an inflatable balloon surrounding the inner lumen. An inflow pipe is disposed within the inflatable balloon and is configured to introduce a refrigerant into the balloon. A thermocouple wire is disposed within the inflatable balloon and positioned adjacent the inflow pipe. The thermocouple wire is configured to measure an internal temperature of the balloon. The cryoablation catheter further includes an isolation guide disposed within the inflatable balloon. The isolation guide includes a central bore configured to receive the inner lumen, an inflow bore configured to receive the inflow pope, and a thermocouple bore configured to receive the thermocouple wire. The thermocouple bore is spaced from the inflow bore along the isolation guide.
