But with innovation comes the critical need to navigate complex SaMD regulatory pathways—an essential step to ensure safety, effectiveness, and market success. Whether developing a biosensor-powered wearable or launching a new digital health platform, understanding global Software as a Medical Device regulations is no longer optional.
In this article, we’ll break down the key components of SaMD regulatory pathways, including insights into the IMDRF SaMD framework, FDA SaMD guidance, and EU MDR compliance requirements. We’ll also offer practical case studies, step-by-step planning guides, and highlight recent regulatory changes to help you move from prototype to market-ready product with confidence.
Understanding SaMD and Connected Devices
As digital health technologies evolve, the distinction between traditional medical devices and Software as a Medical Device (SaMD) becomes increasingly important. SaMD refers to software intended to perform medical functions without being part of a physical medical device. In other words, it operates independently to diagnose, monitor, treat, or prevent disease. This definition, shaped by global frameworks like the IMDRF SaMD framework, sets the foundation for understanding how software alone can be subject to rigorous regulatory scrutiny.
Connected devices, including wearable health trackers, biosensor-enabled monitors, and remote patient management tools, often incorporate SaMD components to deliver clinical value. For example, a wearable heart monitor that uses an app to analyze arrhythmia patterns qualifies as a connected device powered by SaMD. These combinations blur the lines between physical hardware and digital therapeutics, creating new opportunities—and new regulatory challenges.
For developers, the key is recognizing early on whether your product falls under Software as a Medical Device regulations. Failure to correctly classify your product can lead to delays, rework, or regulatory rejection later in the development cycle. Risk categorization, clinical validation, cybersecurity considerations, and lifecycle management all hinge on this initial determination.
As we explore the global landscape of SaMD regulatory pathways in the next sections, understanding this core distinction will help you avoid common pitfalls and align innovation with compliance from the start.
Checklist: Is Your Device a SaMD?
QUESTIONS TO CONSIDER: | YES | NO |
Does your software have a medical purpose? (Examples: diagnosing, monitoring, treating, mitigating, or preventing disease) | ||
Is the software intended to operate independently? (It performs its function without being part of a physical hardware device) | ||
Would the software’s output influence clinical management? (Examples: making diagnostic decisions, suggesting treatments, or informing healthcare interventions) | ||
Is your software more than just a lifestyle or wellness app? (If it directly impacts patient care, it likely qualifies as SaMD) | ||
Would incorrect performance of the software create a health risk? (If yes, regulatory classification and risk management are critical) | ||
Is the software used to control, drive, or influence a medical device? (If yes, it may be regulated as SaMD or as an accessory device) | ||
Is the software stand-alone rather than embedded in a device? (SaMD typically functions separately from hardware, even if it connects to it) | ||
Have you documented the intended use and clinical claims? (Explicit intended use and claims determine regulatory oversight) |
Global Foundations: The IMDRF SaMD Framework
Before diving into regional regulations, it’s critical to understand the global standard that underpins most SaMD regulatory pathways: the IMDRF SaMD framework. Developed by the International Medical Device Regulators Forum (IMDRF), this framework offers a harmonized approach to defining, classifying, and regulating Software as a Medical Device across markets.
What Is the IMDRF SaMD Framework?
The IMDRF SaMD framework provides internationally recognized definitions and guidelines for standalone medical software. It clarifies that SaMD is software intended for one or more medical purposes without being part of a hardware device. By establishing clear criteria, the IMDRF enables regulatory authorities around the world to take a consistent approach when evaluating SaMD products.
Key Principles of the IMDRF SaMD Framework
The IMDRF framework emphasizes three core principles:
- Risk-Based Categorization – SaMD is classified based on the significance of the information it provides and the severity of the healthcare situation it addresses. This risk categorization heavily influences the regulatory burden.
- Clinical Evaluation – SaMD must demonstrate clinical validity, analytical validity, and clinical performance through appropriate evidence.
- Lifecycle Management – SaMD requires continuous oversight, including updates, cybersecurity management, and post-market surveillance, as part of its regulatory compliance.
Why the IMDRF SaMD Framework Matters
Even if your primary target is the U.S. or EU market, aligning your product early with the IMDRF SaMD framework can simplify global expansion and streamline regulatory submissions. Many country-specific guidelines, including FDA SaMD guidance and EU MDR compliance standards, have been built upon IMDRF recommendations.
Understanding these global foundations not only positions your connected device or wearable for success but also ensures your team is prepared for the complexities of evolving Software as a Medical Device regulations worldwide.
U.S. Focus: Navigating FDA SaMD Guidance
For MedTech companies developing software-driven connected devices and wearables, understanding and following FDA SaMD guidance is critical to successfully navigating U.S. SaMD regulatory pathways. The Food and Drug Administration (FDA) applies a risk-based approach to Software as a Medical Device regulation, ensuring that SaMD products are both safe and effective for their intended uses.
Key Documents and Policies
The FDA has released several important documents to clarify regulatory expectations for SaMD, including:
- SaMD: Clinical Evaluation Guidance (developed in collaboration with IMDRF)
- Digital Health Innovation Action Plan
- Pre-Certification Pilot Program (now largely transitioned into broader initiatives)
- Guidance on cybersecurity, real-world evidence, and postmarket management for digital health devices
These documents emphasize that not all healthcare-related software qualifies as SaMD, and they provide frameworks for assessing risk, demonstrating clinical validation, and maintaining product oversight throughout the device’s lifecycle.
Step-by-Step Guide to FDA SaMD Compliance
Successfully bringing a SaMD product to the U.S. market involves several important steps:
Step 1: Confirm SaMD Status
Determine whether your software meets the definition of SaMD under FDA guidance (see our checklist above).

Step 2: Classify the Risk Level
Classify your SaMD based on the potential impact on patient health. Risk levels generally align with Class I (low risk), Class II (moderate risk), or Class III (high risk) device categories.
Step 3: Identify the Appropriate Regulatory Pathway
Depending on the risk classification, select the applicable pathway:
- 510(k) clearance – most common for moderate-risk SaMD
- De Novo classification – for novel, low-to-moderate risk products
- Premarket Approval (PMA) – for high-risk SaMD
Step 4: Prepare Your Submission
Document clinical evidence, software description, cybersecurity controls, risk analysis, and usability testing results. A strong submission should align with both FDA SaMD guidance and general device requirements.
Recent Regulatory Updates
In recent years, the FDA has advanced initiatives through its Digital Health Center of Excellence, further emphasizing the need for dynamic postmarket monitoring, software updates, and cybersecurity vigilance. Developers should anticipate continuous regulatory engagement, even after a product is cleared or approved.
By approaching the U.S. market with a structured, risk-based strategy, connected device innovators can streamline the FDA approval process and avoid costly delays. Partnering with experienced SaMD regulatory specialists, such as Sequenex, can help teams stay ahead in an increasingly complex environment.
EU Focus: Mastering EU MDR Compliance for SaMD
Bringing a SaMD product to the European market requires a strong understanding of the new regulatory landscape under the EU MDR compliance framework. Since its full application in 2021, the European Medical Device Regulation (MDR) has introduced stricter rules for SaMD classification, clinical evaluation, and post-market surveillance, impacting connected devices and wearable developers across the industry.
How SaMD Is Regulated Under EU MDR
Under EU MDR, most SaMD products fall under Rule 11, which governs standalone software intended for diagnostic or therapeutic purposes. As a result, many SaMD applications are now classified as Class IIa, IIb, or even Class III devices—higher risk classes that require rigorous conformity assessments. Unlike under the former MDD framework, self-certification for SaMD is now rare.
Step-by-Step Guide to EU MDR SaMD Compliance
Successfully bringing a SaMD product to the EU market involves many important steps:
Step 1: Determine Qualification and Classification
First, assess whether your software qualifies as a medical device under MDR definitions. Then, apply Rule 11 to determine the appropriate risk classification based on the intended use and potential impact on patient health.
Step 2: Prepare Comprehensive Technical Documentation
Technical documentation must demonstrate compliance across multiple areas, including clinical evaluation, cybersecurity, usability, and risk management. A robust Clinical Evaluation Report (CER) supported by real-world evidence is often necessary.
Step 3: Engage a Notified Body for Conformity Assessment
For Class IIa and higher, a qualified Notified Body must assess the device. Early engagement and clear documentation are crucial to avoid delays during the conformity assessment process.
Step 4: Plan for Post-Market Surveillance and Vigilance
Ongoing monitoring, incident reporting, and annual updates to the technical file are mandatory under MDR. SaMD developers must implement post-market surveillance systems early to meet these requirements.
Recent Regulatory Changes and Deadlines
The European Commission has extended certain MDR transition deadlines, giving manufacturers more time to certify legacy devices. However, SaMD products classified as new under MDR (i.e., previously unregulated software) must comply immediately. Staying informed about evolving EU guidance is critical for maintaining EU MDR compliance and successful market entry.
By proactively aligning with MDR expectations, connected device and wearable developers can accelerate approvals and build trust in the European healthcare ecosystem. Teams that leverage continuous compliance processes—such as those built into Sequenex’s development models—can significantly reduce regulatory risks.
