摘要:
A near critical fluid based cryoablation system comprises a cryoablation catheter for creating a lesion in tissue. A cryogenic fluid is transported under pressure through the catheter. A controller adjusts the pressure from a relatively high (e.g., near critical) pressure to a substantially lower pressure based on a condition during the catheter activation. In one configuration, the pressure is modulated based on the temperature of the catheter. When the temperature of the catheter reaches a target temperature, the pressure is reduced.
