Application of Tantalum Capillaries in Medical Devices

The application of tantalum capillaries in the field of medical devices is mainly based on the excellent biocompatibility, corrosion resistance and mechanical properties of tantalum metal. Specific applications include:
• Orthopedic implants: Tantalum and its coatings are widely used in orthopedic implant materials, such as artificial joints, bone plates, bone nails, etc. Tantalum coatings can promote cell adhesion, proliferation and differentiation, enhance bone integration, and improve the biocompatibility and corrosion resistance of implants.
• Coating materials: Tantalum and its oxide and nitride coatings (such as TaC, TaCN, TaN) are used for surface modification of titanium alloy and cobalt-chromium alloy implants to enhance the corrosion resistance, antibacterial and bone conduction properties of the materials and extend the life of the implants.
• Medical device protective tubes and thin tubes: Tantalum capillaries can be made into thin wires or thin tubes due to their good ductility and corrosion resistance. They are used to manufacture protective tubes, catheters, etc. in medical devices, and are suitable for medical devices with high precision and high stability requirements.
• Cardiovascular and interventional devices: Tantalum coatings and tantalum capillaries are used in cardiovascular stents, interventional catheters and other devices. Their biocompatibility and mechanical toughness can reduce adverse reactions after implantation and improve device performance1.
• Radiofrequency and laser surgical equipment accessories: Tantalum capillaries can be used to manufacture medical laser fiber sheaths and catheters in radiofrequency ablation equipment to transmit laser energy or high-frequency current, meeting the requirements for high temperature resistance, corrosion resistance and biosafety of materials during surgery.
In summary, tantalum capillaries are mainly used in the field of medical devices for coatings and structural materials of orthopedic implants, protective tubes and catheter manufacturing, as well as high-end interventional and surgical equipment, giving full play to their excellent biocompatibility, corrosion resistance and mechanical properties.
