Abstract

The invention discloses a chemical ablation balloon catheter, a chemical ablation combination product and an ablation method. The chemical ablation balloon catheter comprises a catheter body and a balloon, the catheter body is provided with a guide wire cavity, a perfusion cavity and a filling cavity, the far end of the catheter body is provided with a guide wire outlet, a perfusion outlet and a filling outlet, and the perfusion cavity and the filling cavity are communicated in the direction from the near end to the far end of the catheter body. The filling outlet, the perfusion outlet and the guide wire outlet are sequentially distributed so that the radial size of the catheter body can be continuously reduced in the direction from the near end to the far end, and the balloon is connected to the catheter body and communicated with the filling outlet. The balloon has a first filling state when the balloon is not filled and a second filling state when the balloon is filled. The chemical ablation balloon catheter is convenient to use, saves time and labor, and improves the operation efficiency.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a chemical ablation balloon catheter, a chemical ablation combination product and an ablation method. Background technique [0002] Atrial fibrillation is the most common clinical tachyarrhythmia. The probability of stroke, heart failure and cardiovascular death in patients with atrial fibrillation will increase significantly, and the disability and fatality rate are extremely high, which seriously threatens people's health. At present, radiofrequency ablation has become the first-line treatment for some patients with paroxysmal atrial fibrillation, but persistent atrial fibrillation is the biggest difficulty in the field of atrial fibrillation ablation because of its high recurrence rate and difficulty in ablation. This is largely due to radiofrequency ablation. The intervention of energy on epicardial structures such as Marshall's vein is insufficient and incomplete. The vein o...
