Abstract

The invention provides an ablation catheter and a method using the same to implement ablation. The ablation catheter comprises an ablation electrode, a catheter body, an operation handle and a control processing system which are connected sequentially, the control processing system comprises a radio frequency transmitting system and a microwave signal processing system, the radio frequency transmitting system sends out an ablation radio frequency signal which is transmitted to ablation tissue through the ablation electrode, the ablation electrode receives a microwave signal from the ablation tissue and transmits the microwave signal to the microwave signal processing system, and the ablation electrode can serve as a transmitting antenna of the ablation radio frequency signal and a receiving antenna of the microwave signal, so that temperature change of the ablation tissue can be presented truly and timely without affecting controllability of the catheter. The ablation catheter is simple in machining process and low in cost, and operating safety is improved to some extent.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an ablation catheter and an ablation method using the ablation catheter. Background technique [0002] Today, it is possible to use catheter ablation technology to treat diseases such as arrhythmia and resistant hypertension. For example, radiofrequency ablation is to send an ablation catheter with electrodes through veins or arteries to a specific site that needs to be ablated, and release radiofrequency current to cause local tissue coagulation necrosis, so as to block the transmission of abnormal electrical signals or block sympathetic nerves. . In radiofrequency ablation, local tissue coagulation necrosis is caused by heating tissue, therefore, the control of tissue temperature is particularly important. When the temperature is too low, such as less than 50 degrees, it is difficult for the tissue to form an effective ablation lesion, that is, the electrical signal i...
