Nitinol Tubing in Medicine

Nitinol Properties

Nitinol tubing is special in medicine because it has many helpful features. It belongs to the nickel-titanium shape memory alloys group. Nitinol can stretch and bend, then go back to its original shape when heated. Doctors like nitinol tubing because it bends many times and does not break. The tubing does not rust because it has a protective layer. This makes it safe to use inside the body for a long time. Nitinol tubing is light but also strong. Thin tubes made from nitinol can move through tricky paths in the body. It works well with the body and does not cause bad reactions. This helps people heal faster. The tubing changes with body temperature, so medical devices work better during procedures. Nitinol tubing does not wear out easily, so it lasts longer in tough medical jobs. These features make nitinol tubing a great choice for medical devices and implants.

Note: Nitinol tubing can return to its shape after being bent. This is important for medical devices used in small surgeries.

The tubing is very useful in surgeries that do not need big cuts. It helps patients heal faster and feel less pain. The table below shows where nitinol tubing is used and how common it is in these surgeries:

Doctors get good results with nitinol tubing in devices that remove blood clots, fix heart valves, and treat with ablation catheters. Studies show patients do better, stay in the hospital less, and have fewer problems. The tubing’s ability to bend and stay strong helps devices move through blood vessels and return to their shape. Nitinol tubing is used in many medical areas, like heart stents and dental tools. More doctors want nitinol tubing as they do more small surgeries. F2063 standards make sure every tube is safe and works well for these important uses in medicine and engineering.

ASTM Standards for Nitinol

ASTM F2063 Overview

ASTM F2063 is a set of rules for nitinol tubing. These rules are for tubing used in medical devices. The standard tells what chemicals and features the tubing must have. Makers must follow these rules to make good nitinol tubing for doctors.

• ASTM F2063 says nitinol tubing needs 54.5% to 57% nickel. The rest is titanium.

• Oxygen and nitrogen together must be less than 500 parts per million. This keeps the tubing pure for medical use.

• Inclusions in the nitinol melt cannot be bigger than 39 micrometers. This helps stop problems that could break the device.

• The tubing must be smooth. The roughness should be about 1-2 micrometers (Ra). This helps the tubing stay in place and connect with body tissue.

• The TiO2 oxide layer on the tubing helps stop rust. It also helps the tubing stick to body parts.

• Makers must lower fretting wear. This keeps nickel from coming out, which is safer for patients.

• The way the tubing is made must not add new problems. This makes sure the tubing is always high quality for medical use.

ASTM F2063 makes sure every nitinol tube is made with care. The rules help keep the tubing strong and safe for medical work.

The table below shows what chemicals and features nitinol tubing must have for ASTM F2063:

These rules help make sure nitinol tubing is always good quality. ASTM F2063 helps doctors trust the tubing in their devices.

Biocompatibility and Corrosion Resistance

Nitinol tubing must be safe for the body. Medical grade ASTM F2063 tubing should not hurt people. Tests check if the tubing is safe for the body. These tests look for things like cell damage, allergies, and other bad effects. The tests show if the tubing is safe for medical tools.

The tubing must also not rust inside the body. Medical devices can stay in the body for a long time. The tubing must not break down in body fluids. ASTM F2129 is a test to see if the tubing can resist rust. This test uses fake body fluids to check how strong the tubing is. If the tubing does not break down, it is safer for patients.

• Electropolished nitinol tubing resists rust better than oxidized tubing.

• The TiO2 oxide layer helps stop rust and helps the tubing join with body tissue.

• Fewer and smaller inclusions mean less chance for rust spots. This keeps the device strong.

• How smooth the tubing is, how much surface it has, and test settings all change how well the tubing resists rust.

ASTM standards for nitinol make sure every tube is safe and works well. These rules help protect patients and make medical devices last longer.

Fatigue and Strength Testing

Nitinol tubing must be strong and last a long time. Medical devices bend and move a lot in the body. ASTM F2082 and other rules tell how to test nitinol tubing for these jobs.

Testing steps include:

• Cutting samples from nitinol tubing and making them smooth.

• Putting samples in fake body fluid at 37°C to copy body heat.

• Bending and loading the samples over and over, like in real use.

• Running tests until the tubing breaks or up to 10 million bends. At least six samples are tested each time.

• Using computer models to check stress and looking at the tubing under a microscope.

These tests find out how long nitinol tubing can last. The results show if the tubing can handle tough jobs in the body. Nitinol’s special features depend on the right mix of chemicals and a smooth surface, as ASTM F2063 says.

New ASTM rules for nitinol help keep up with new medical devices. Better safety, less rust, and longer life mean fewer problems for patients.
