Why is it called Nitinol? Where can it be used?

You may be a medical professional or a patient you could be curious to know what nitinol is and how it can be used. Nitinol is a metallic component used in many medical applications like orthopedic staples, medical devices and shape-memory alloys.

Shape memory alloy

Like other materials, shape memory alloys are capable of remembering their previous shapes. The two-way effect of shape-memory can be created by applying thermal or mechanical forces. These alloys are recognized to possess superior mechanical and wear resistance properties. These alloys are often used in the manufacture of valves, wires for orthopedic use, and medical implants.

Shape-memory materials are usually made through vacuum arc melting casting, and induction melting. These materials possess unique crystal structures that permit them to expand and return to their initial shape after the heating process.

The Shape Memory alloy is also known to have super-elastic properties. They are employed in fields like robotics, orthopedics as well as neurology. They also are used in aerospace and automotive industries. Shape-memory alloys' properties can be seen in their extensive use in medical devices, for example, heart valves and stents. These materials can also be used in the chemical processing industry.

Shape-memory alloys are made from a blend of nickel as well as titanium. They are considered engineering materials. They are extremely suited to the automotive industry, as well as having excellent wear and corrosion resistance.


There have been a variety of studies conducted to examine the mechanical properties of Nitinol. These studies have shown that the product has mechanical hysteresis. Also, it has shape memory properties. These properties are beneficial to enhance the design of stents.

Nitinol is a component in many different stents. These stents may vary in diameter, thickness, strut thickness, and design. They can also also be manufactured using additive manufacturing technology. This allows manufacturers to develop customized stents to meet specific patient needs.

Recent studies have focused on what the mechanical property of Nitinol's Stents. These studies make use of a combination of test techniques that are commonly used, such as bench-top-based mechanical tests and finite element models. These techniques allow researchers to simulate complex loading conditions in-vivo. By using computational modeling researchers can identify which design aspects contribute to more efficient performance.

One study examined the physical properties of six stents made of Nitinol. The stents were assessed based on their stiffness, resistance to bending and axial compressibility. The stents ' diameters ranged from 5 to 8 mm. The stents were held by rods inside when compressed.

Staples for orthopedics

There have been numerous studies that have investigated the mechanical characteristics of nitinol used in orthopedic staples. A new generation of nitinol-based compression staples has been successful in hindfoot arthrodesis.

Nitinol compression staples may be used with bone grafting and can reduce the recovery after surgery. However, this procedure might not be an appropriate choice to patients with weak bones. Small bones are more difficult to join, and a nonunion may lead to arthritis that develops early.

The nitinol-memory compression staple is relatively new to the carpal bone fixation market. The staple is made out of an ultraelastic TiNi alloy, which allows for natural compression while healing. It can be used to give adequate compression, without causing any damage to cartilage's proximal dorsal.

Compression staples also serve for fixing subtalar joints and talonavicular fuses. Additionally, they can be used to treat foot injuries in other conditions. They can also be used to perform osteotomy procedures. They could not be secure enough for small bone applications and may disrupt osteotomies.

The new generation of Nitinol compression staples have been demonstrated to be safe and effective for hindfoot arthrodesis. The study also looked at the distinctions between double and single-staple design. Newer-generation Nitinol staples had significant radiographic union.

Medical devices

In the past few years, medical professionals began to appreciate the numerous advantages of making use of Nitinol to make medical products. It is a popular material due to its exceptional elasticity. This allows it to return to its original size when under pressure. The properties of Nitinol make it a good option for orthopedic implants, catheters, and stents.

Nitinol's advantages in medical devices are substantial and it has opened many new markets for medical devices. However, the characteristics that the substance has pose several problems. Knowing the risks that could be associated with the material is vital.

The Federal Drug Administration (FDA) recently released a draft guidance for medical device manufacturers about how to design and test devices using Nitinol. The guidance outlines the most significant suggestions for medical devices that use the material.

The scope of the guideline covers all medical devices containing Nitinol. It provides the necessary information manufacturers must disclose in their premarket filing, including details about the design, production, in addition to the testing and evaluation of these devices. The document also includes information on Nitinol's biocompatibility.
