What is Nitinol and Where is it Used
What exactly is Nitinol? Where is it Used?
Whether you are a medical professional or a patient, you may be interested to know what nitinol is and how it can be used. Nitinol metal is used for a wide range of medical applications, such as orthopedic staples, medical devices and shape-memory alloys.
Metal with memory shape
Contrary to other types of materials, shape-memory alloys can remember their former shape. This double-sided effect of shape memory can be created by applying forces or heat treatments. These alloys have superior wear and mechanical properties. These alloys are often used in orthopedic wires, valves, in medical and surgical implants.
Shape-memory alloys typically are created through the process of vacuum arc melt, casting, and induction melting. These materials feature distinctive crystal structures that enable them to alter their shape and return them to their original shape upon heat.
Shape memory alloys are also recognized to possess super-elastic properties. They are used in various fields such as orthopedics, robotics as well as neurology. They are also used in the automotive and aerospace industries. The properties of these alloys has led to their widespread application in medical devices such as heart valves or stents. These materials are also used in the chemical processing sector.
Shape-memory alloys are made from a combination of nickel and titanium, and they are considered to be engineering materials. They are well-suited for the automotive industry and also offer excellent corrosion and wear resistance.
There have been a variety of studies conducted to study the mechanical properties of Nitinol. These studies have shown that the material is able to exhibit mechanical hysteresis along with shape memory properties. These properties are useful to enhance the design of stents.
Nitinol can be found in a variety of different stents. These stents vary in size, thickness, strut thickness, and design. They can also produce using additive manufacturing technology. Manufacturers can create customized stents specifically for certain patient needs.
Recent studies have looked into those properties in the Nitinol Stent's mechanical structure. These studies make use of a combination of standard test techniques, such as bench-top-based mechanical tests as well as finite-element modeling. These techniques enable researchers to simulate complicated loading conditions in vivo. By using computational modeling researchers can determine the design characteristics that contribute to better performance.
A study was conducted to determine the mechanical properties of six stents made of Nitinol. The stents are compared based on their resistance, bending stiffness, and axial compression. The stents ' diameters varied from 5 to 8 mm. They are supported by rods inside during compression.
Staples for orthopedics
Multiple studies have been conducted to study the mechanical properties of nitinol-based orthopedic staples. A new type of nitinol compression staples has shown to be successful in arthrodesis of the hindfoot.
Nitinol compression staples may be employed in conjunction with bone grafting and may hinder post-surgery healing. However, the procedure may not be the best option for patients suffering from small bones. Small bones are difficult to join, and nonunion may result in the onset of arthritis.
The nitinol-memory compression staple an extremely new product to the carpal bone fixation market. The staple is made from a superelastic TiNi alloy and permits natural bone healing by compressing. It provides adequate compression while also preventing damage to the distal dorsal cartilage.
Compression staples are also utilized in the treatment of subtalar joint and talonavicular Fusions. In addition, they are used to treat foot injuries in other conditions. They can also be used to perform osteotomy procedures. They could not be secure enough for applications of small bones and could disrupt osteotomies.
Newer nitinol compression staples have been found to be both safe and effective for hindfoot arthrodesis. The study also examined the differences between single and double-staple constructs. The latest generation of nitinol staples showed higher radiographic union rates.
In the past few years, the medical profession began to recognize the many advantages of the use of Nitinol within medical instruments. The material is known for its super-elasticity, which allows it to stretch back into its original shape under pressure. The properties of Nitinol makes it a suitable option for orthopedic implants catheters and stents.
Nitinol's benefits for medical devices are significant and the material opens up numerous new medical markets. However, the characteristics of the material create several obstacles. Understanding the risk factors that may be involved to the material is critical.
The Federal Drug Administration (FDA) recently released a draft guidance for medical device manufacturers in the design and development of test devices using Nitinol. The guidance outlines the most significant tips for medical devices using the material.
The guidance includes all medical devices that use nitinol. The guidance outlines the data manufacturers must disclose in their premarket submission, and includes details on how to design, manufacture, along with the tests of equipment. It also contains information regarding the biocompatibility of Nitinol.
