Cryogenic balloon catheter having heating function

A cryogenic balloon catheter having a heating function, comprising:

• a catheter body and an external power source,
• an outer wall of the catheter body comprising an inner layer,
• a middle layer and an outer layer disposed in sequence from inside to outside, and the middle layer comprising a metal woven mesh that is connected in a power supply circuit of the external power source,
• wherein the metal woven mesh is a grid-like metal-wire woven mesh formed by a plurality of metal wires,
• wherein the grid-like metal-wire woven mesh has a proximal end and a distal end, and each metal wire in the grid-like metal-wire woven mesh is led out from the proximal end to be connected to a positive electrode or a negative electrode of the external power source, a conducting ring is disposed at the distal end of the grid-like metal-wire woven mesh, and each metal wire in the grid-like metal-wire woven mesh is connected to the conducting ring at the distal end, such that the plurality of metal wires of the grid-like metal-wire woven mesh form a parallel circuit.
