In the field of minimally invasive interventional medical devices, the selection of materials directly determines the performance boundaries of the devices. Among the various medical metal materials, why has nickel-titanium alloy wire become the preferred choice for high-end device design? Shanghai Wewei Technology will explain its three irreplaceable core performance advantages.
Advantage 1: Unparalleled "Super Elasticity"
Resistance to bending: Interventional guidewires and catheters made with this material are less prone to permanent bending when navigating tortuous blood vessels, ensuring unobstructed device function.
Resistance to Compression: When used in woven vascular stents, the stent can quickly rebound after being compressed within the body, maintaining vascular patency—a feat unachievable with materials like stainless steel.
Advantage 2: Precise "Shape Memory Effect"
Self-expanding stent: The stent can be compressed into a fine delivery system at low temperatures and, upon reaching the target site, automatically expands into a preset tubular structure under the influence of body temperature, enabling minimally invasive implantation.
Smart Devices: Can be used to develop various temperature-responsive precision instruments, such as thrombus retrieval devices and cardiac occluders.
Advantage 3: Outstanding "Flexibility and Biocompatibility"
Flexibility: While possessing high strength, nickel-titanium alloy wires also exhibit excellent flexibility, allowing them to naturally bend along the contours of blood vessels and significantly reducing the risk of damage to the vascular walls.
Biocompatibility: High-quality medical-grade nickel-titanium alloy exhibits excellent blood and tissue compatibility, having passed rigorous ISO 10993 biocompatibility certification to ensure clinical safety.
