In the rapidly evolving landscape of medical technology, the materials used to craft devices are as crucial as the innovative designs themselves. Resonetics stands at the forefront by offering advanced nitinol materials and processing that are redefining the boundaries of medical device performance and reliability.
What is Nitinol?
Nitinol, an alloy of nickel and titanium, is renowned for its unique properties of superelasticity and shape memory. These characteristics allow nitinol to undergo significant deformation and return to its original shape. This makes it an ideal material for a range of medical applications, particularly in minimally invasive procedures.
Why Nitinol for Medical Devices?
The medical industry demands materials that are not only biocompatible but also highly reliable and versatile. Nitinol fulfills these requirements and more:
- Superelasticity: Nitinol can undergo deformation up to 10-30 times that of conventional metals and recover its original shape, providing flexibility and durability in medical devices.
- Shape Memory: This property enables devices to be designed in one shape, deformed for deployment, and then return to their functional shape at body temperature.
- Biocompatibility: Nitinol is highly biocompatible, which is essential for medical implants and devices that interact closely with biological tissues.
Material Grades and Inclusions
Impurities exist inside the nitinol from the melting process. These are most commonly carbon and oxygen and form secondary-phase particles during solidification. They are referred to as inclusions. The goal is to limit the size of inclusions because large inclusions can significantly degrade the mechanical properties of the material. Resonetics offers three different grades of nitinol material, with different inclusion sizes and area.
| ASTM | Standard | Redox | Enduro | ||
| Nitinol ingot | Max Inclusion Size | 39 um | 30 um | 20 um | 12 um |
| Inclusion Area Fraction | 2.8% | 2.0% | 1.2% | 0.5% |
