Nitinol’s key role in medical devices of the future

Nitinol's versatility has led to its use in a wide array of medical devices. In addition to guidewires, nitinol is used in flexible retrieval devices and instruments, vascular filters, and permanent implants. These devices benefit from nitinol's ability to endure repeated stress without losing shape or performance. Nitinol’s adaptability allows it to be crimped, bent, or coiled into tight configurations, easing insertion through minimally invasive methods. In cardiovascular treatments, nitinol filters capture blood clots and prevent embolisms. These filters collapse for deployment and expand inside blood vessels to perform life-saving functions. Nitinol is also promising in steerable medical devices like endoscopes and catheters.

However, manufacturing nitinol in a cost-effective way while maintaining the highest quality requires specialist capabilities. Even the slightest deviation during production can alter the performance of the material. Understanding the impact of cold work, heat treatment, strain rate, and number of cycles is essential for optimizing the stress-strain behavior of nitinol.
