Stainless Steel Wire in Medical Applications



Stainless steel wire is a versatile material widely used in various industries, including the medical field. Its unique properties make it suitable for medical applications where strength, durability, and corrosion resistance are crucial. In this article, we will explore the properties of stainless steel wire and its diverse range of medical applications.


Properties of Stainless Steel Wire


Stainless steel wire possesses several key properties that make it ideal for medical applications:


Corrosion Resistance: Stainless steel wire exhibits excellent resistance to corrosion, making it suitable for use in environments where exposure to bodily fluids or sterilization agents is common.


Strength and Durability: Stainless steel wire is known for its high strength-to-weight ratio and durability, allowing it to withstand the demanding conditions encountered in medical applications.


Biocompatibility: Stainless steel wire is biocompatible, meaning it is well-tolerated by the human body and does not cause adverse reactions or tissue irritation.


Sterilization Compatibility: Stainless steel wire can withstand various sterilization methods such as autoclaving, ethylene oxide (EtO) sterilization, and gamma irradiation without significant degradation or loss of properties.


Hereafter a short summary of key modern uses in medical applications:


Vascular therapy: continuous improvements of medicine allow minimally invasive intervention through arteries and veins. Stainless steel wires are found in intra-arteria stents, angioplasty catheters, guide wires and diagnostic catheters, aneurysm clips, etc...

Orthopedics applications: this broad field covers trauma, reconstructive, spinal & sports medicine. Stainless wires can be found in fracture fixations, spinal devices, nails, bone pins and screws, cerclage cables, suture wire.

Endoscopic medical devices: this fast growing field targets efficiency, comfort through minimally invasive procedures. Strands and cables made of fine stainless steel wires are used for: biopsies, gallstone removal, support of colonoscopy, retrieval of foreign objects in airways, laparoscopic surgery...

Orthodontics: this specific field of applications often uses shaped stainless steel wires for arch wire, self-litigating brackets, springs. Both the aesthetic and the mechanical properties of stainless steel are at work there… Related field of “implant dentistry” also makes use of stainless steel wire.

Surgical and diverse applications: Stainless steel wire is often used for post-surgery staples, suture wire and needles, stylets. Another important field of use of stainless steel spring wire is the spring mechanisms of syringes, medical or self-injection systems for diabetes, allergic reactions. Stainless steel wire is thus an important item in the increasingly diversified and fast growing medical field, in surgery, implants and sophisticated devices.

Medical Applications of Stainless Steel Wire


Stainless steel wire finds extensive use in various medical applications, including:


Surgical Instruments

Surgical instruments often incorporate stainless steel wire due to its strength, flexibility, and corrosion resistance. Wires are used in instruments such as retractors, forceps, surgical clips, and suture passers.


Orthopedic Implants

Stainless steel wire is utilized in orthopedic implants, including bone plates, screws, and intramedullary nails. Its strength and biocompatibility make it an excellent choice for providing structural support and stability in orthopedic procedures.


Catheter Guides

Stainless steel wire is employed as the core material in catheter guidewires. These thin, flexible wires help navigate catheters through blood vessels or other body channels, providing guidance for various medical procedures.


Dental Applications

Stainless steel wire plays a crucial role in dental applications. It is used for orthodontic wires, dental brackets, and archwires, providing support and alignment in orthodontic treatments.


Suture Wire

In surgical procedures, stainless steel wire is often used as suture wire for wound closure. It offers excellent tensile strength, allowing secure and long-lasting wound closure.


Advantages of Stainless Steel Wire in Medical Applications


The use of stainless steel wire in medical applications offers several advantages:


Biocompatibility: Stainless steel wire is biocompatible, minimizing the risk of adverse reactions and promoting tissue compatibility.


Corrosion Resistance: The corrosion resistance of stainless steel wire ensures long-term performance and reduces the risk of implant failure or complications.


Strength and Durability: Stainless steel wire's high strength and durability provide reliable support and stability in various medical devices and implants.


Sterilization Compatibility: Stainless steel wire can withstand repeated sterilization processes without compromising its properties, ensuring the safety and efficacy of medical devices.


Stainless steel wires are increasingly present in medical applications which rely on their attractive combination of corrosion resistance, durability and mechanical properties.


Stainless Medical Wire


The main domains of applications are primarily the increasingly sophisticated field of “medical devices” used in diagnosis, investigations and innovative surgical techniques such as laparoscopy, and the more traditional areas of implants as well as surgical miscellaneous parts.


Stainless steel wire can be in various presentations (round, flat or shaped wire) and forms (mesh, braided, straightened cut lengths, cables). Main grades used are 302, 304, 316L most often as the ESR-remelted grades 302 V, 304V, 316 LVM. Also used are grades 630 (17-4 PH) and 440C. Wire sizes are mostly in the smaller dimensions.
