What is Nitinol? Where is it used?
No matter if you're a medical practitioner or a patient you could be curious in knowing what nitinol actually is and where it's used. Nitinol is a metal used in a number of medical applications, including medical devices, orthopedic staples and shape-memory alloys.
The alloy that forms the shape memory
In contrast to other substances, shape memory alloys are able to remember their former shape. This double-sided effect of shape memory can be achieved through forces or heat treatments. These alloys are recognized to possess superior mechanical and wear resistance properties. These alloys are often used in valves, orthopedic wires, as well as medical implant.
Shape-memory alloys are typically made by vacuum arc melted casting, or even induction melt. They have distinct crystal structures that enable them to alter their shape and return them to their original shape following heat.
The Shape Memory alloy is widely recognized for their super-elasticity. They are used in applications such as orthopedics, robotics as well as neurology. They also are used in the automotive and aerospace industries. The characteristics of shape-memory alloys has led to their widespread usage in medical devices such as heart valves or stents. They also find applications in the chemical processing sector.
Shape-memory materials are the combination of nickel with titanium, and they are considered to be engineering materials. They are highly suited to the automotive industry, and also offer excellent corrosion and wear resistance.
A variety of studies have been conducted to determine the mechanical properties of Nitinol. The results of these studies show that the materials have mechanical hysteresis and shape-memory properties. These properties could be useful to improve stent design.
Nitinol is a component in many different stents. These stents vary in size along with thickness, thickness and design. They can also produce by using additive manufacturing technology. This allows manufacturers to create customized stents specifically for certain patient medical conditions.
Recent research has focused on how Nitinol's stents' mechanical characteristics are affected. The studies utilize a combination of standard test techniques, like bench-top tests as well as finite-element modeling. This technique allows researchers to simulate complicated in-vivo loading conditions. With the help of computational modeling, researchers can discover which design aspects contribute to improved performance.
A study was conducted to determine the mechanical properties of six stents made of Nitinol. They were compared on their stiffness, resistance to bending, and axial compression. The stents had diameters ranging from 5 to 8 millimeters. They had been supported using internal rods in compression.
Staples of orthopedics
A variety of studies have explored the mechanical performance of nitinol to make orthopedic staples. A new generation of nitinol compression stitches has shown to be successful in hindfoot arthrodesis.
Nitinol compression staples can be used alongside bone grafting. They may hinder post-surgery healing. However, the procedure may not be a suitable option to patients with weak bones. Small bones can be difficult to fuse, and any nonunion could cause early-onset arthritis.
The nitinol memory compression staple is relatively new to the market for carpal bone fixation. The staple is made of an ultraelastic TiNi alloy and allows for natural bone healing by compressing. It is able to provide adequate compression while protecting the cartilage proximal to the dorsal.
Compression staples are also used to stabilize subtalar joints as well as talonavicular Fusions. They are also used for other foot disorders. They can also be used to perform osteotomy procedures. They may not be stable enough for use on small bone or may interfere with osteotomies.
New-generation Nitinol compression staples are been found to be safe and effective for hindfoot arthrodesis. The study also looked at the advantages and disadvantages of double and single-staple constructs. The newer nitinol staples have an extremely high rate of radiographic union.
Several years ago, medical professionals came to recognize the many advantages of using Nitinol for medical equipment. Nitinol is a material that is known for its exceptional elasticity. This allows it to stretch back in its original shape under stress. The characteristics of Nitinol make it a viable choice for orthopedic implants, stents, and catheters.
The advantages of Nitinol for medical devices is significant and the substance has opened many new markets in medicine. However, the characteristics of the material present various issues. Understanding the potential risks with the material is crucial.
The Federal Drug Administration (FDA) recently released a draft of guidance for medical device manufacturers for how to design and evaluate devices using Nitinol. It lists the most important requirements for medical devices made of Nitinol.
The scope of the guidelines includes all medical devices that use nicotine. It defines the information manufacturers need to disclose prior to submission, including information on the manufacturing, design, along with the tests of equipment. It also contains information regarding the biocompatibility and biocompatibility of nitinol.
