Abstract

The invention provides an ablation catheter. The ablation catheter comprises an operation handle, a catheter body and an ablation electrode which are connected from the near to the distant, wherein a far end of the ablation catheter is separately connected with a closure device; the operation handle controls the closure device to be separated from the ablation electrode; after closure device completes closure, the closure device falls off from the ablation electrode, and the ablation electrode is exposed for ablation, so that closure and ablation can be realized in one operation. The processing process of the ablation catheter is simple, the cost is low, the operation is simple and convenient, and the ablation catheter doesn't have more severe influence on the operation mode, the operation time and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ablation catheter. Background technique [0002] Currently, there are two main ways to treat atrial fibrillation. One is to restore sinus rhythm, such as catheter ablation, and the other is to control heart rate combined with thrombosis prevention. The embolism caused by atrial fibrillation mainly comes from the left atrial appendage. Even if the sinus rhythm is restored after treatment, the left atrial appendage may be in shock, and thrombus may still be formed, leading to the risk of ischemic stroke. Therefore, occlusion of the left atrial appendage can greatly reduce the risk of stroke. At present, the left atrial appendage can be occluded through intracardiac intervention, using an occluder with a special structural design, using guiding technology to establish a percutaneous access to the left atrial appendage, and then transporting the occluder by a conveyor, an...
