Key Properties of MRI-Safe Nitinol Tubing

Non-magnetic nature and MRI compatibility

Nitinol is special because it is non-magnetic. This makes it safe for use in MRI machines. Regular metals can cause problems with MRI systems, but nitinol does not. Medical devices made from nitinol work well during MRI scans without causing issues.

Did you know? MRI machines use strong magnets that can pull on certain metals. This can create safety problems or blurry images. Nitinol avoids these problems because it works perfectly with MRI systems.

Tests have shown nitinol works great in MRI settings. For example:

• Scientists tested nitinol tubing in a 3T MRI machine using a model.

• They tracked nitinol wires and fixed small errors in measurements.

• Results showed nitinol tubing works well without hurting image quality.

Because of this, nitinol tubing is perfect for stents, guidewires, and catheters. These tools need to work safely in MRI machines.

Biocompatibility and corrosion resistance

Nitinol tubing is safe for the human body because it is biocompatible. It also doesn’t rust, so it lasts a long time. Research shows many benefits:

• Nitinol lowers the chance of bad reactions, making it great for implants.

• Tests like ASTM F2129 prove it resists corrosion and stays strong.

Polished nitinol has smooth surfaces that stop blood clots from forming. This process also reduces nickel release, which can be harmful. These features make nitinol tubing a top choice for stents and other medical devices.

Flexibility and nitinol shape memory alloys

Nitinol is very flexible because it is a shape memory alloy. It bends under pressure but returns to its original shape when heated. This happens because it changes between two crystal forms: austenite and martensite.

Tests show nitinol’s shape memory works well:

The Bend Free Recovery test also finds the Af Temperature, which helps make high-quality nitinol. Its flexibility lets nitinol tubing move easily through the body’s pathways.

Tip: Nitinol devices adjust to body movements, making procedures safer and more comfortable.

Fatigue resistance and durability

In medical devices, being strong and lasting is very important. Materials must handle repeated use without breaking or failing. Nitinol is special because it resists wear and tear extremely well. This means devices made from it keep working even after lots of bending and stretching.

Nitinol can bounce back to its original shape after being bent. It handles twisting and bending many times without snapping. This makes it perfect for things like stents and implants, which need to be both strong and flexible. For instance, nitinol tubing in blood vessels shows a strain recovery of 5.62% and works successfully 98% of the time. These numbers prove it’s dependable in tough medical situations.

Another reason nitinol lasts long is that it doesn’t rust. Medical tools often touch body fluids, which can damage other materials. But nitinol stays strong and doesn’t break down, so it works well for a long time. This makes it a great choice for stents and guidewires that need to stay reliable for years.

Nitinol also works safely in MRI machines. It doesn’t react to magnets, and its strength ensures it performs well. These features make nitinol tubing a trusted material for advanced medical tools.

Note: Using nitinol means devices last longer, need fewer replacements, and help patients recover better while saving money on healthcare.
