Custom Medical and Surgical Springs

We provide an expansive selection of standard parts that are ready to ship. If you can't find what you need in our part catalog, we also offer custom springs and wire forms solutions for medical applications.

We offer many custom options for 316 stainless steel springs, the most popular spring material for medical devices. This material provides superior corrosion prevention performance and features smooth surfaces that are easy to clean.

Custom Component Manufacturing

We offer unmatched expertise in designing and fabricating customized springs for medical devices and surgical applications. Our metallurgical expertise allows us to manufacture precision wire from products as small as 0.004” in diameter, which are ideal for small springs used in surgical equipment. We also have dedicated, high-speed machines that scale spring production to the high product volumes most commonly required for consumable medical and surgical equipment such as syringes.

Whether you are in your project's design or procurement phase, we are ready to partner with you to create springs that meet the unique needs of your medical equipment. We always strive to minimize development lead times to get products to you as quickly as possible.

Springs in Medicine


Springs are found in equipment all over the medical device industry, from surgical tools to orthopedic and implantable medical devices. Some of the most common applications are as follows:

  1. Handheld Surgical Instruments: Any handheld device, such as a wire retractor used to hold back tissue during surgical operations, likely has a spring integrated into it to provide the mechanical force required for the device to function.

  2. Implantable Devices: Small springs may be found within medical devices implanted directly into a patient’s body, such as pacemakers and implantable cardioverter defibrillators (ICD). Springs function as tiny electrodes within these devices.

  3. Orthodontic Devices: Springs are found in specific orthodontic equipment because they can efficiently provide the steady force required to move teeth gently.

  4. Syringes and auto-injectors: An auto-injector is a device that delivers a concentrated, high dosage of a drug, sometimes through a patient’s clothing. The spring provides the force needed to inject the medication in such devices. For example, EpiPens are auto-injectors that quickly provide high drug dosages directly to tissue to prevent anaphylaxis.

  5. Medical pumps and valves: Pumps and valve equipment deliver metered drug dosages to patients, typically via a catheter or intravenously. They are also used to perform blood transfusions.

  6. Medical robotic technologies: Many robotic equipment or machinery pieces need springs to function correctly. All components used within such robotic equipment, including springs, must be fabricated from the highest quality, medical-grade materials and cleanliness standards.

  7. Hearing Aids: Springs are most commonly found within the battery compartments of hearing aids, providing the conductive path to ensure proper device function. They may also be found in the device's tiny audio switches and relay circuits.

  8. Ventilators: Like medical pumps and valves, ventilators are complex life-sustaining medical equipment. Springs in ventilators help control airflow and enable proper valve functionality.

  9. Prosthetics: Springs are integral in dozens of prosthetic devices, such as knee joint replacements.

What We Offer

Reliable Manufacturing Services

Century Spring offers state-of-the-art manufacturing equipment and in-house expertise to create custom medical spring solutions engineered to withstand any environment and meet the most demanding medical device tolerance requirements. We also bring extensive design for manufacturability (DFM) expertise to your project.

We also have cutting-edge computational equipment simulation and testing techniques, such as CNC compression self-monitoring and coiling machinery. These capabilities enable us to deliver durable, reliable products across many custom sizes and styles. Our manufacturing services also include complete prototyping and tooling assistance.

Our team will work directly with you to create, refine, and optimize spring designs to fit specific tolerance, performance, and use case conditions. We are ready to partner with you today to bring your high-performance medical springs to life.

Quality Materials

We offer hundreds of in-stock springs fabricated from the most advanced surgical-grade spring materials, such as stainless steel, Nitronic®, Elgiloy®, titanium, and even a broad selection of high-performance plastics, such as PEEK. We also offer additional spring material options, such as Beryllium Copper, Cobalt Chrome, and Phosphorus Bronze, all suited for medical devices.

However, 316 stainless steel springs are our most popular product for surgical equipment applications because they are chemically inert to surrounding environments and fluids. This material also offers excellent strength and durability and a smooth surface finish, making the products easy to sterilize.

We offer passivation surface treatment options for many of our in-stock 316 stainless steel spring products to further increase your spring's corrosion resistance. Lastly, we provide specialized finishing, cleaning, packaging, and shipping options if your application demands it.

FAQs About Medical Springs

What is the difference between stainless steel alloys (300/302 and 316)?

The main difference between stainless steel alloys 300/302 and 316 involves corrosion resistance. Alloy 300/302 is a general-purpose stainless steel with good corrosion resistance in applications with light exposure to water or mildly corrosive mediums. In contrast, 316 stainless steel has more corrosion resistance against a wide range of fluid medium applications, which is why it is the favored alloy for medical and food-grade applications.

What are the primary advantages of passivated stainless steel springs?

The primary advantage of passivated Stainless Steel springs is the chromium oxide surface layer, which is the chemical mechanism that provides excellent corrosion resistance to stainless steel. This surface layer prevents additional oxygen from reacting with the iron below. Passivating is a secondary chemical process that increases this surface layer to ensure it is sufficiently thick and unbroken. As such, it is strongly recommended for springs that will be subjected to highly corrosive mediums.
