Abstract
Apparatus, including a probe, containing a first lumen and a second lumen and having a distal end that contacts tissue of a living subject. A fluid supply delivers a cryogenic fluid through the first lumen to the distal end and receives cryogenic fluid returning via the second lumen. A temperature sensor is located at the distal end. A pressure sensor located at a proximal end of the first lumen measures a pressure of the cryogenic fluid. A processor controls a delivery rate of the cryogenic fluid from the fluid supply, so that, when a temperature measured by the temperature sensor is less than a preset guard temperature, the delivery state is a preset low rate, and when the temperature measured by the temperature sensor is greater than or equal to the preset guard temperature, the delivery rate is set in response to a pressure measured by the pressure sensor.
