Abstract: A cryogenic balloon catheter having a heating function, the cryogenic balloon catheter comprising a catheter, an external power source, wherein an outer wall of the catheter comprises an inner layer, a middle layer and an outer layer, which are sequentially arranged from inside to outside, the middle layer comprising a metal woven mesh, and the metal woven mesh, the temperature controller and the external power source forming a power supply circuit. In the cryogenic balloon catheter, the middle layer of the outer wall of the cryogenic balloon catheter is provided with the metal woven mesh having a heat conduction function, and the metal woven mesh is connected to the external power source, such that the metal woven mesh can generate heat after being powered, so as to ensure that the temperature of the outer surface of the catheter is maintained within set temperatures, thereby ensuring the cryogenic ablation effect.
