Nitinol Tubing Properties
Superelasticity
Superelasticity makes nitinol tubing special in medical devices. Devices with superelastic nitinol tubing can bend many times and do not stay bent. Digital Image Correlation shows nitinol spreads out strain when it is loaded again and again. This stops kinking and helps nitinol tubing keep its shape under pressure. Temperature checks help set the right shape, which is important for superelasticity. The stress-strain curve of superelastic nitinol tubing has a flat part. In this part, the tubing gives almost the same force even when stretched a lot. This helps stents and catheters move through tricky blood vessels. Devices get both flexibility and shape memory, so they work well in less invasive surgeries.
Shape Memory
Shape memory is a key feature of nitinol tubing. When you bend nitinol, it goes back to its first shape when heated. Tests show medical grade nitinol tubing can handle stress from 500 MPa to 900 MPa and still keep its shape memory. Heat-treated nitinol gets over 90% recovery by the second try and 96% by the tenth, with steady strain above 6.5%. Devices with nitinol tubing can stretch up to 10%. This is much more than the 1% limit for stainless steel. This means nitinol tubing keeps its shape and works well after many uses. Its flexibility and shape memory help devices stay safe and reliable for patients.
Evidence Type | Metric / Result | Description / Context |
|---|---|---|
Elastic Deformation Capacity | Up to 10% strain | Nitinol tubing can stretch up to 10%, which is much more than 1% for stainless steel, showing great shape memory. |
High-Cycle Fatigue Strain Limit | 0.4% to 0.8% strain | Shows nitinol tubing lasts a long time under repeated stress, making it reliable. |
Clinical Vessel Crossing Success Rate | 98% | The Silverway guidewire works well in blood vessels, showing high reliability. |
Catheter Delivery Success Rate | 92% | Catheters are placed successfully most of the time, so devices work well. |
Patient Implant Rejection Rate Reduction | 30% lower than traditional metals | Nitinol tubing is less likely to be rejected by the body, so it is safer for implants. |
Biocompatibility
Biocompatibility is very important for materials in medical devices. Medical grade nitinol tubing is very biocompatible and does not rust easily, so it lowers the chance of bad reactions. Studies like DAWN and PARTNER 3 show nitinol devices help more people live better and longer than old treatments. For example, the DAWN trial found 49% of people were independent at 90 days with nitinol, but only 13% with standard care. Nitinol tubing also lowers implant rejection by 30% compared to other metals. Trials show nitinol stents hurt vessel walls less and lower the chance of the vessel getting blocked again. These results show nitinol tubing is very safe and does not rust, so it is great for long-term implants.
Clinical trials proved nitinol stents work for tough artery problems.
Tests looked at how much force was needed, how stents opened, and what happened to the tissue.
After treatment, doctors saw less vessel wall damage and fewer blockages.
Corrosion Resistance
Corrosion resistance helps nitinol tubing last longer and stay safe in the body. Lab tests show nickel ions drop to 75 parts per billion after special cleaning. Oxygen and carbon in medical grade nitinol tubing stay below 60 ppm and 20 ppm. After polishing, the surface is very smooth at 0.1 micrometers or less. Tubing smaller than 0.3 mm can be made with a size difference of only ±0.005 mm. Long tests in liquid show nitinol tubing does not get pitted under body-like conditions. It lasts over 600 million heartbeats without breaking, so it is very strong. Studies show better processing makes the surface cleaner, which helps with safety and stops rust. These features make sure nitinol tubing stays safe and works well in medical devices.
Medical Device Performance
Minimally Invasive Solutions
Nitinol tubing helps doctors do less invasive surgeries. It is very flexible and can return to its shape. Surgeons use nitinol devices to move through the body with less harm. Studies show a 97% success rate for these procedures. At 12 months, 96.7% of aneurysms are closed. The DAWN Trial found 49% of patients using nitinol tools could live on their own after 90 days. Only 13% could with regular care. This means nitinol tubing helps save lives. Devices like neurovascular catheters, guidewires, and stents use nitinol tubing. These tools work well and are very precise. Nitinol tubing can stretch 7% and return 4.16%. This helps devices fit the body and lowers the chance of hurting blood vessels.
