There are several conventional terms for radiofrequency ablation catheters, namely ST (SmartTouch), SF, TC (Tacticath) big heads, and these terms are mainly used to describe the different types and functions of radiofrequency ablation catheters.
For example, there are SmartTouch catheters from Biosense Webster and Tacticath catheters from ST Jude; This variability is reflected in the physical design of the catheters, but also in their function and range of applications.
The above three ablation heads act on linear ablation techniques, especially in atrial fibrillation**. This technique restores the heart's normal rhythm by creating a continuous ablation line to isolate the abnormal electrical signal and stop it from spreading. The three types of catheters, ST, SF, and TC, can all be used for linear ablation, but they are suitable for different work needs that involve the precision, depth, and scope of ablation.
From a ** perspective, it is extremely important to understand the characteristics and platinum-iridium content of the different radiofrequency ablation catheters (ST, SF, TC). It is important to know that platinum-iridium alloy is widely used as an important material in the design and manufacturing process of radiofrequency ablation catheters; Different types of catheters have different concentrations of platinum iridium, and the value of the large head of the ablation catheter with high platinum iridium content will be much higher.
