Microfabrication for Medical Device Manufacturing

For almost 25 years, MultiSource Manufacturing LLC has worked to engineer and fabricate precise parts, components, and full assemblies for the medical device industry. Medical equipment production requires a level of perfect accuracy, strict design specifications, and bio-safe engineering knowledge. No matter what kind of devices we manufacture, from surgical equipment to implantable devices, we adhere to the highest industry standards, and our own goals for quality and safety during every step in the production process. Our engineering team and manufacturing technicians understand the importance of a reliable, well-made product for all industries, but especially for the medical device field. The quality of a medical device when put to use in a hospital, emergency room, or other treatment center can mean life or death for a patient. To eliminate the potential of any of our devices compromising a patient’s health and well-being, we follow a set of meticulous but basic standards for quality and precision. Many of our medical device manufacturing operations also utilize microfabrication processes to build intelligent electronic designs and tools for bio-integration.

Uses of Microfabrication

There are many uses for microfabrication when it comes to medical device manufacturing. From a biochemical standing, microfabrication is key for creating solutions for cell biology treatments, biosensors, and other components that involve medical procedures at a molecular level. Our microfabrication capabilities operate on a slightly larger scale than molecular biology, but we still work to build parts that are almost invisible to the naked eye. Tolerances often run as tight as +/-0.001″ (+/-0.0025mm) on our medical device production floor.

Much of our microfabrication for medical devices works with semiconductor and electronics fabrication. Some processes we utilize in our microfabrication operations include:

Thin-film deposition

Made from silicon, metals, or plastics, thin films can be used in microcomponents for masking, structure, subtractive manufacturing, and more. Thin films deposited on surfaces are typically fused with chemical reactions, but can be attached with physical operations. Common films use silicon dioxide or silicon nitride, both dielectric substrates (electrical insulators).

Wet processing

For semiconductors and other microcomponents, wet processing is a critical part of developing a precise design. Wet processing immerses parts into an etching solution, which chemically removes areas of a chip or part that is not masked with specific films or other photoresist agents. We also use wet processing to apply strip lines and other parts of a microchip and wafer system.

Electronics integration

With our capabilities for semiconductor microfabrication and our medical device manufacturing skills, we can pair microcomponents with electrical systems. Circuits, chip boards, electrodes, capacitors, insulators, and other parts of electronic medical devices of all kinds rely on our microfabrication and precision in the full assembly of parts, from catheterization, ablation, and other implantable devices to drug delivery systems and pharmaceutical packaging.

Improving Manufacturing for Medical Equipment Used in Cardiac Treatments

The medical technology industry is a rapidly expanding one, but unlike other industries growing just as quickly, medical equipment has unmatched demand for precision, reliability, and safety. Because the quality of medical equipment directly affects the health and wellbeing of patients, including those who are unable to speak for themselves (such as children and the elderly), the medical industry has to meet a standard of ethical production and testing practices. At MultiSource Manufacturing LLC, we are dedicated to providing unparalleled quality for components and assemblies used to fabricate medical equipment that is distributed globally. Our goal is to continually improve our practices and products for all areas of the medical industry we provide for, including cardiac medicine and treatments.


A large portion of the components and assemblies we manufacture are utilized in the cardiology branch of medicine for cardiac treatments ranging from minor to aggressive heart issues. The medical equipment we fabricate on our state-of-the-art production floor is used in various treatments, including:


Atrial Fibrillation: This cardiac affliction manifests as an irregular heartbeat caused by the upper chambers of the heart beating rapidly and out of sync with the lower chambers. This increases the risk of a stroke or heart attack. The components we manufacture are used in the equipment that produces medications or catheterization systems that treat atrial fibrillation.


Cardiac Ablation: This is a primary treatment for atrial fibrillation and other causes of an irregular heartbeat when medications fail. Using a catheter system, surgery, or a combination of both, surgeons can create scar tissue in specific areas of a patient’s heart. This scarring alters the rhythm of the heartbeat, stabilizing and syncing the chambers. Our components are used in many various types of ablation equipment.


Implantable Devices: Our components are used in the fabrication of ICDs (implantable cardioverter defibrillators), one of the most commonly used implantable devices in the United States. Additionally, we manufacture equipment used in other implantable devices, including pacemakers and coronary stents, for treating cardiac health issues.


Catheterization: Cardiac catheterization can be used to test for heart conditions or treat an existing condition. The long, thin tubing inserted into arteries, heart blood vessels, or veins allows blood flow to and from the heart when that flow would otherwise be unreliable. We manufacture several components used in cardiac and other catheterization systems.


Surgical Navigation: In many surgical operations, including almost all cardiac and open-heart surgeries, highly advanced navigation systems are critical. These navigation systems require extreme precision and trusted performance because they introduce another factor into the human body during surgery. The components we fabricate for surgical navigation devices are highly accurate and well-engineered products.

Understanding Guidelines for Surgical Steel Used in Quality Medical Manufacturing

Among the many high-quality services MultiSource Manufacturing, LLC, provides with our network of facilities is the design and fabrication of medical device components. When it comes to manufacturing parts and components for medical devices, it’s critical to the health and safety of every patient across the world to establish extremely high standards for reliability, quality, and precision. MultiSource is dedicated to maintaining manufacturing practices that exceed standards for the medical device industry, including responsible materials-sourcing for all projects we take on. For many medical manufacturing projects, the parts and components require surgical-grade steel in order to fabricate the most reliable medical devices.


Surgical-grade steel is a nonspecific term for a variety of stainless steels used in the fabrication of many different tools, including most medical devices and other biomedical purposes.


Surgical Steel


The surgical steel utilized in most medical applications includes:


  1. Austenitic 316: This surgical steel is an alloy of nickel, chromium, and molybdenum that is highly resistant to corrosion and has adequate strength for medical devices and implants that are pressure-bearing. Alloys also used for pressure-bearing biomedical implants are typically titanium (Ti6Al4V, specifically), but the surgical steel 316 is also suitable, and it’s more economical than titanium.
  2. Martensitic 440 and 420: These steels are used for cutlery production, but they are also well suited for surgical-grade applications of the material. As high-carbon steels alloyed with chromium, 440 and 420 surgical-grade steels are very resistant to corrosion, though less so than 316. However, they are much harder than 316. Because they are harder than 316 but not as resistant to corrosion, 440 and 420 are often used to manufacture surgical implements and medical cutting tools.


The MultiSource network utilizes 316, 440, and 420 surgical-grade steels as well as a range of additional industry-approved and safely-sourced materials to fabricate many key components that go into a variety of medical devices. From surgical equipment to implantable devices, medical providers can rely on MultiSource to manufacture the highest quality parts and components that are the most reliable in the long term thanks to the materials used and the expertise of our fabricators.


Some of the more unusual and advanced medical manufacturing projects that we take on, like designing and producing parts for surgical navigation or ablation devices, benefit especially from our surgical-grade materials and our excellence in fabrication because of their unique complexities and relatively new introduction into medicine.
