Frozen balloon ablation catheter

The utility model discloses a frozen balloon ablation catheter, and belongs to the technical field of medical instruments. The frozen balloon ablation catheter is characterized by comprising a balloon catheter, wherein the front end of the balloon catheter is cooperatively provided with a latex balloon, a pre-shaped memory metal net rack is arranged in the latex balloon, the balloon catheter is internally provided with a capillary tube, and the front part of the capillary tube extends into the cavity of the latex balloon. The frozen balloon ablation catheter is simple in structure, safe to operate and simple, the latex balloon is unfolded under the action of the memory metal net rack so as to be tightly attached to the wall of the renal artery intima, once successful cryoablation can radically damage the external wall sympathetic nerve network cluster of the renal artery at the attached section of the balloon, so that omission and recidivation opportunities are reduced, and operation steps and operation time both are reduced; moreover, freezing causes less injury to the tissues, so that the danger caused by piercing, thrombus and renal artery stenosis can be reduced to a great extent, the operation tolerance is improved, and the treatment effect is improved remarkably.
