Ablation and mapping system, control device and multi-electrode ablation and mapping device

Abstract

The invention provides an ablation and mapping system, a control device and a multi-electrode ablation and mapping device. The system comprises: an ablation and mapping control device is used for generating and outputting multi-loop RF energy or single-loop RF energy according to the selection of the user and the set procedure; a stimulation signal is generated according to the predetermined procedure, the measurement result obtained from the measurement performed by the multi-electrode ablation and mapping device utilizing the stimulation signal is received, and whether the ablation is successful is judged according to the measurement result; the multi-electrode ablation and mapping device performs RF ablation for the part to be ablated according to the obtained multi-loop RF energy or single-loop RF energy; the part to be ablated is measured through the stimulation signal generated by the control device, and the measurement result is fed back to the control device. Application of the ablation and mapping system, the control device and the multi-electrode ablation and mapping device can control the ablation degree better, guarantee the ablation effect, decrease risk, reduce times of ablation, and decrease the surgery difficulty.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an ablation and mapping system, a control device and a multi-electrode ablation and mapping device. Background technique [0002] Atrial fibrillation is a common cardiac arrhythmia. Atrial fibrillation is caused by excessive abnormal electrical signals received by the atrium, causing the atrial beat to be significantly faster and extremely irregular. Atrial fibrillation affects the pumping function of the heart, which means that the brain and other organs of the body do not receive enough blood supply. Over time, atrial fibrillation can cause a decline in cardiac function, causing irreversible cardiac damage. When atrial fibrillation causes insufficient pumping function of the heart, some blood will pool in the heart to form a blood pool, which becomes viscous and forms a thrombus. If part of the clot breaks off, it may cause a stroke. In fact, stroke rates are five times highe...

Problems solved by technology

However, the ablation effect of the radiofrequency ablation device disclosed in the above patent application is limited, and it usually needs to be ablated multiple times at one location to achieve a better electrical isolation effect, which increases the complexity of the operation and prolongs the operation time
