The critical role of radiofrequency ablation catheters in heart disease** is attributed to the multiple metal fittings inside, which are designed and selected based on their specific functions and needs in the medical process. The following is a detailed description of the metal fittings commonly found in radiofrequency ablation catheters and their material compositions:
Platinum-iridium tip: This is the most important part of a radiofrequency ablation catheter. Platinum-iridium alloys were chosen for their excellent electrical conductivity, high melting point and good corrosion resistance. The platinum-iridium alloy tip is responsible for transferring the current and performing a precise ablation operation.
Stainless steel bracket: The stents for catheters are usually made of stainless steel, providing the necessary mechanical strength and flexibility. Stainless steel is a commonly used material for medical devices, which has certain corrosion resistance and biocompatibility.
Metal wires: The internal wires of the catheter are usually made of copper or silver and are used to transmit electrical signals. These metals have good electrical conductivity and are ideal for electrical signal transmission.
Titanium alloy connectors: In some ablation catheter designs, titanium alloys may also be used as connectors or fixings. Dititanium alloys are widely used in medical instruments due to their lightweight, high strength and biocompatibility.
These metal fittings enable the radiofrequency ablation catheter to function efficiently in complex cardiac procedures. Platinum-iridium metal tips are particularly valuable, and platinum and iridium, as rare metals, can be extracted and reused through a professional process after the medical instrument is scrapped.
Despite the complexity of the design of radiofrequency ablation catheters, each metal fitting is selected based on its specific role in the medical process. In the process, the extraction of these metal fittings not only contributes to the sustainable use of resources, but also reduces the impact on the environment, while ensuring the effectiveness of precious metals such as platinum and iridium.
