A few years ago, some doctors in a hospital in Denmark faced a bizarre confusion. Their newly installed hospital software asked them to choose between “left leg” and “correct left leg,” instead of left and right leg. The confusion was caused by a simple mistranslation. By 2018, 62% of physicians using the software complained that they were not satisfied with it, and 71 physicians signed a petition demanding its removal.
The mix-up sounds funny until one realizes that this was a real hospital system, used on real patients, where confusion like this could lead to a fatal mistake.
This language problem in complicated systems shows exactly why the art of medical device localization is taken so seriously across industry.
In this blog, we will cover what medical device localization is, the compliance rules that revolve around it, and why it needs professional expertise and not just a quick word-to-word translation.
What Is Medical Device Localization?
Medical device localization is the process of adapting all the content connected to a medical device, like manuals, labels, and software interfaces, so it works correctly and is understood in a new language and region.
Localization also adapts:
- Units of measurements
- Date and number formats
- Cultural context and phrasing
- Legal terms to match local regulations
Many technical medical terms don’t have a word-for-word translation in different languages. A poorly localized medical device seems unnatural, confuses the person using it, and can even cause patient harm.
Why Is Medical Device Localization So Important?
Medical devices are useful systems used by doctors, nurses, and patients. They are completely reliant on the instructions provided to use these devices effectively. If these instructions are unclear or incorrect, the consequences can turn out to be dangerous.
- Patient safety is directly at risk: A mistranslated warning, dosage, or instruction can put patients in harm’s way.
- Regulatory approval depends on accurate localization: Health authorities in every country require legally compliant documentation before approving the sale of a medical device.
- Trust between manufacturers and users depends on clarity: Doctors, patients, or any other person using the device need to fully understand how it works to safely operate it.
- The financial risk is too high: Delays in regulatory approvals or product recalls can cost medical device manufacturers time and money in every market.
The Denmark examples show us that these risks are real. Even well-funded software can run into serious trouble when localization isn’t done professionally.
The Medical Device Localization Process
Medical device localization usually follows a structured and efficient process to reduce errors and ensure accuracy.
Step | What Happens |
| Initial Planning | Deciding target languages and understanding who will use the content, professionals or patients. |
| Subject Matter Review | Identifying the specific medical field involved, such as clinical, diagnostic, or surgical. |
| Source Material Collection | Gathering all original documents, manuals, and interface text. |
| Translation, Editing, Proofreading | Trained linguists translate the content, followed by editing and proofreading. |
| Quality Assurance | Checking for formatting, terminology consistency, and accuracy across all files. |
| Testing | Reviewing the final localized version for errors, especially in software interfaces. |
What Are Some Compliance Requirements for Medical Device Localization?
Medical devices are among the most regulated products in the world. Hence, localization needs to meet strict compliance standards depending on the target markets.
- ISO Certifications: Many translation agencies follow specific ISO standards to ensure quality and consistency. Some crucial ISO certifications include:
- ISO 9001 for general quality management.
- ISO 13485 for medical devices specifically.
- US FDA Regulations: In the United States, the Food and Drug Administration (FDA) classifies medical devices into three risk categories:
- Class 1: For low-risk devices, like bandages or surgical gloves.
- Class 2: For medium-risk devices, like blood pressure cuffs.
- Class 3: For high-risk devices, like pacemakers or vascular grafts.
Higher-risk devices typically require more rigorous documentation and translation accuracy, since the margin of error is smaller.
- EU Medical Device Regulation (MDR): In the European Union, manufacturers must provide all device documentation in all 24 official languages under the EU MDR. This law has been in full enforcement since May 2021. Some documents that need to follow this regulation are:
- User manuals and instructions for use
- Device labelling and packaging
- Regulatory and technical documents
Manufacturers risk being backlisted across the EU if they choose not to follow this regulation.

Which Documents Generally Require Medical Device Localization?
A wide range of content needs accurate localization before a device enters global markets.
Some of these documents include:
- Instructions for use and user manuals
- Device labelling and packaging
- Software interfaces and on-screen prompts
- Regulatory compliance documents
- Marketing and training materials
Each of these documents plays a different role, but all of them need to be clear, accurate, and consistent across every language.
Need for a Professional Medical Device Translation Agency
With such high-stakes documents involved, working with a general translator is not enough. A trusted medical device translation agency brings the specialized expertise needed for accurate and high-quality results.
Reliable experts offer:
- Native linguists with medical and technical knowledge.
- Familiarity with regulatory requirements across different countries.
- Multi-step quality checks to catch errors before they reach the market.
- Experience in adapting complex interfaces and not just written documents.
- A common glossary across manuals and other documents to maintain consistency and avoid confusion.
Relying on medical device localization services helps manufacturers reduce the risk of approval delays, confusion, or safety issues.
Frequently Asked Questions (FAQs)
What is medical device localization?
It is the process of adapting and translating medical device documentation, labelling, and interface so it works correctly in a new language and region.
How is localization different from translation?
Translation only focuses on texts and words, while localization also adjusts units, formats, and cultural context to fit the target market.
Why is medical device localization so high-risk?
Because errors in instructions or labeling can directly affect patient safety and lead to serious harm.
What is the EU MDR language requirement?
The EU MDR requires manufacturers to provide device documentation in all 24 official EU languages.
What are the FDA’s medical device classes?
Devices are classified into three classes, namely class 1 (low-risk), class 2 (medium-risk), and class 3 (high-risk).
What documents commonly need medical device localization services?
Some common documents that need medical device localization are user manuals, device labelling, software interfaces, regulatory documents, and training materials.
What risks do manufacturers face with poor medical device localization?
Poor medical localization can lead to confusing instructions, incorrect warnings, delayed regulatory approvals, and in some cases, patient harm.
What is ISO 13485, and why does it matter?
ISO 13485 is a quality standard specific to medical devices. It is often used by translation agencies to ensure accuracy and consistency.
Why should manufacturers work with a professional translation agency instead of a general translator?
A specialized translation agency ensures regulatory compliance, accuracy and consistency in terminology, and strict quality control.
