The disclosure relates to a cryoablation catheter and a cryoablation system. The cryoablation catheter comprises a catheter body and a freezing unit. The catheter body comprises a cold-source fluid input lumen and a cold-source fluid output lumen, both extending in an axial direction of the catheter body, and the freezing unit is arranged at a distal portion of the catheter body, and comprises a first balloon in fluid communication with the cold-source fluid input lumen and the cold-source fluid output lumen, and a second balloon arranged external to the first balloon with the length of the first balloon being less than the length of the second balloon. When the first balloon and the second balloon are dilated, a cavity is formed between the first balloon and the second balloon, to prevent the energy transfer in a space of the freezing unit corresponding to the cavity.
