Developing and manufacturing a new medical device is a complex and lengthy process. It includes a variety of steps from the discovery to development and commercialization. Contract manufacturing organization (CMOs) you offer vital services to medical device OEMs, startups and more. This may include product development and manufacturing support to biotech and pharmaceutical companies or manufacturing medical products for these companies. No matter what specific services you provide, it is critical to ensure consistent quality and reduce overall cost and time-to-market for your clients.
The core strength of many CMOs lies in years of manufacturing experience and significant investments in manufacturing infrastructure. These provide the ability to deliver consistent product quality under all circumstances.
However, things get complicated while manufacturing medical devices that are either inserted or implanted within the body. Such devices require surface modification to ensure their performance and reliability within the body. Additionally, they need to comply with strict regulations enforced by the FDA (U.S. Food and Drug Administration), EMA, ISO, and other international high authority bodies.
As a CMO you may lack an in-house, fully developed coating facility as well as internal polymer chemistry or medical coating expertise. So, to ensure the highest product quality, prevent product failures and ensure quick approvals from the regulatory bodies, many CMOs partner with trusted medical coatings service providers, such as Hydromer®, Inc. This allows them to bring high-quality medical products to the market while focusing on their core strengths.
In this article we explore how CMOs can use a full-service medical coatings services partner and the benefits of doing so. First, we look at the challenges associated with medical device coating development and application. Then we will discuss how a coatings partner like Hydromer®, Inc. can help CMOs overcome various coating-associated challenges and achieve their commercial goals.
How Medical Coatings Can Make Or Break Your Devices
First, it is helpful to understand the importance of medical coatings to a successful medical device. In other words, why should a CMO such as yours put extra emphasis on selecting and applying the right coating.
Most medical devices are made up of metals, glass, polymers, and ceramics. Left in their natural state these materials can interact with surrounding tissues and cause harmful reactions. This would cause serious health consequences. That’s why medical devices are coated with surface modification coatings, such as hydrophilic coatings. Such coatings significantly enhance the device performance, improve biocompatibility, and ensure that they meet the most stringent regulatory standards.
Here’s how hydrophilic medical coatings improve medical devices and implants:
- Product performance and advanced functionality: Medical coating technology is rapidly advancing. Advanced hydrophilic coatings offer excellent lubricity and can be custom-formulated to provide several functionalities, such as anti-thrombogenicity, antimicrobial properties, drug-eluting capabilities, and much more.
- Regulatory compliance: Devices that are either inserted or implanted must adhere to the most stringent regulatory standards in the healthcare industry. Coatings can help even the most complex and high-tech medical devices gain approvals from agencies like the FDA and EMA. They have become the most popular choice to help medical devices meet strict compliance.
- Long-term cost savings: The right coatings can help significantly minimize recalls and warranty claims. They are a proven way to extend the life of medical instruments and increase brand reputation over time.
- Biocompatibility: The base materials (metals, glass, polymers, etc.) can react adversely with the surrounding biological tissues. In some cases, it may lead to life-threatening situations. Coatings help medical devices designed using such materials become both non-toxic and non-carcinogenic. They create a physical barrier between the device surface and the surrounding biological tissue or environment.
These are just a few of the many benefits of applying coatings to medical devices. They can also help enhance cell adhesion, corrosion resistance, thromboresistance, and more.

Why Should CMOs Partner With A Medical Coatings Service Provider
One of the critical aspects of manufacturing high-performance and reliable medical devices is surface modification. It modifies the surface properties of base materials to make the medical devices more safer.
From startups to OEMs, everyone often looks for a reliable third-party vendor to apply coatings to medical devices because they possess a deep understanding of polymer chemistry, regulatory requirements, analytical testing, and more. For example, Hydromer® offers unmatched in-house polymer chemistry expertise and the resources to develop medical coating solutions that make their clients’ ground-breaking products a success.
As a CMO you can also leverage such coating services provided by industry experts, such as Hydromer®, Inc. But before you make any decision, let us understand the difficulties encountered by a CMO while formulating and applying surface modification coatings to medical devices.
Challenges CMOs Face While Coating Medical Devices
Developing medical coatings internally is challenging and it can also be very expensive. In addition, it may distract from your core strengths, result in poor product quality, and impact product time-to-market. Here are just some of the challenges CMOs face when developing and applying coatings in-house.
1. Equipment and Infrastructure Costs
Setting up your own coating facilities and in-house team can be challenging. The purchase and maintenance costs of skilled technicians and specialized equipment is considerable and may represent a substantial investment.
Below are just some of the costs associated with the development and application of medical coatings:
- Raw material costs
- R&D personnel and equipment investments
- Production costs
- Testing equipment and personnel expenses
- Regulatory costs
In short, an in-house coating facility may be unfeasible for many CMOs due to both the initial and ongoing operational costs.
2. Material Compatibility: R&D, Polymer Chemistry, Formulation Expertise
Medical devices are made from a variety of base materials (substrates), as discussed earlier. Each substrate has distinct chemical and physical properties that need to be considered.
As a result, coating chemistry needs to be fine tuned to ensure proper adhesion, stability, and performance. In order to formulate quality hydrophilic medical coatings a CMO would need a dedicated team to research and develop different chemistries for each material. This team also has to spend a considerable amount of time developing coatings with multifunctional benefits.
For example, Hydromer® hydrophilic coatings are customized to offer enhanced biocompatibility, antimicrobial properties, drug-eluting capabilities, etc. Gaining the expertise to develop such coatings requires a significant investment in talent, equipment, and more.
3. Coating Application Issues: Experienced Contract Coating Services
A non-uniform coating layer poses serious risks both during and after operational procedures. As such, manufacturers are required to ensure proper coating thickness and coverage for the desired performance and safety.
Achieving uniform thickness becomes even more complicated in the case of medical devices with complex geometries.
In addition, properly preparing, applying, and quality testing medical coatings requires significant know-how.
Hydrophilic coating companies like Hydromer®, Inc. can successfully coat both the inner diameter (ID) and outer (OD) lumens of medical devices such as catheters due to their decades of experience and use of advanced tools.
4. Complex Regulatory Requirements: Need For Regulatory Expertise
There are various regulations enforced by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and other international counterparts. Each medical device manufacturer must comply with these regulations and gain approvals from various government bodies to sell their devices to specific markets.
Additionally, the regulations related to medical devices that come in contact with the biological environment change frequently. Things get frustrating when the submission is disapproved due to minor mistakes.
All of these issues can lead to frustrated customers, damaged reputation, and lost business.
5. Rigorous Testing and Validation
Time-to-market is largely affected by failures in the testing and validation phases. And, if and when faulty products reach end-users, it can ruin a brand’s reputation.
