Artificial intelligence (AI) is transforming healthcare in ways that were unimaginable just a decade ago. From wearable ECG monitors that track heart rhythms in real time to continuous glucose monitors that predict glucose spikes, AI-driven tools are becoming central to modern medicine. Recognizing this growing trend, the U.S. Food and Drug Administration (FDA) released new draft guidance in 2025 focused on the development and marketing of AI-enabled medical devices.

This guidance provides a clear framework for companies developing these technologies—especially those creating connected, adaptive, and learning systems. It emphasizes transparency, lifecycle management, and safety. For innovators and manufacturers, understanding this document is essential to stay compliant and competitive in a rapidly evolving industry.

Why Is the FDA’s 2025 Guidance So Significant?

How the AI Medical Device Landscape Has Changed

AI-enabled medical devices are different from traditional tools because they can learn, adapt, and update over time. These devices often rely on large volumes of data and advanced algorithms to analyze health metrics continuously. For example:

  • Wearable ECG monitors can detect irregular heart rhythms automatically.
  • Continuous glucose monitors can predict trends and help users adjust their insulin levels.
  • Predictive diagnostic devices can alert healthcare professionals about early signs of disease.

Because these systems evolve with use, old regulatory pathways are no longer sufficient. The FDA’s 2025 guidance ensures that safety, accuracy, and fairness remain priorities across the entire product lifecycle.

Why Developers Should Pay Attention

If your company is working on AI-powered medical devices, the guidance provides clarity on how to handle development, validation, and post-market monitoring. It also offers a way to prevent delays and compliance challenges.

By integrating strong measurement controls, developers can ensure their devices perform consistently and safely. A great place to explore these systems and frameworks is through Vergent Products’ measurement controls resources, which highlight the importance of precision and verification across device design.

What Does the 2025 Draft Guidance Cover?

The FDA’s draft guidance is titled “Artificial Intelligence-Enabled Device Software Functions: Lifecycle Management and Marketing Submission Recommendations.” It outlines how companies should manage the design, development, and marketing of AI-based devices throughout their life cycle.

Here are the major themes of the document:

1. Device Description and Functionality

Manufacturers are expected to clearly explain how their AI component works. This includes:

  • The data used for training and validation.
  • The expected input and output.
  • The workflow of the device and how users will interact with it.

For instance, an AI-enabled ECG monitor must detail how it detects heart irregularities, how the algorithm learns from data, and how it minimizes false alerts.

2. Risk Management and Bias Control

AI systems can be prone to bias if trained on incomplete or non-representative data. The FDA stresses the need to evaluate and mitigate bias early in development. Risk management must also account for how the device behaves in different settings and among diverse user groups.

3. Data Governance and Validation

Good data management is essential. Developers must ensure their data is high-quality, securely stored, and traceable. Validation should confirm that the AI performs as intended in both laboratory and real-world conditions.

4. Transparency and Labeling

AI-enabled devices must be transparent about how they make decisions. The FDA expects labeling to explain what the AI does, its limitations, and how users should interpret its results. For example, a continuous glucose monitor must indicate whether predictions are estimates or real-time readings.

5. Lifecycle Oversight and Change Management

Because AI can evolve after deployment, developers must outline how updates will be handled. The FDA encourages companies to prepare a Predetermined Change Control Plan, which defines how software updates, retraining, or algorithm adjustments will be tested and verified.

A comprehensive approach to lifecycle control mirrors practices used in industrial and mission-critical systems—an area explored further in Vergent Products’ industrial and critical environment section.

How Does the Guidance Affect Wearable ECG Monitors and Continuous Glucose Monitors?

AI in Wearable ECG Monitors

AI-powered ECG monitors use continuous data collection and algorithmic analysis to identify cardiac irregularities. Under the FDA’s new guidance, manufacturers must demonstrate that their algorithms:

  • Are trained on diverse, representative ECG data.
  • Maintain accuracy when users move or exercise.
  • Minimize false alerts while preserving sensitivity.
  • Include a plan for post-market monitoring and updates.

Developers should describe how their models work, what type of data they rely on, and how users will receive alerts or notifications. Transparency and usability are as important as accuracy.

AI in Continuous Glucose Monitors (CGMs)

Continuous glucose monitors increasingly use AI to analyze trends and predict glucose fluctuations. To comply with the FDA’s expectations, developers must show that their systems can handle real-world variations such as diet, activity level, and sensor placement.

Safety is critical for CGMs since they often influence treatment decisions. The guidance emphasizes the need for continuous monitoring, validation, and performance tracking over time.

Using proven frameworks from medical device manufacturing can help ensure this reliability. You can explore some of these approaches in Vergent Products’ medical devices section.

What Steps Should Developers Take Now?

Preparing early for the FDA’s updated expectations will save time and prevent costly rework later. Here are the key actions to take:

Step 1: Form a Cross-Functional Development Team

Combine expertise from software engineering, regulatory compliance, clinical science, and quality assurance. AI-enabled devices require collaboration across multiple disciplines.

Step 2: Plan for Data Diversity and Quality

Build datasets that represent different demographics, clinical settings, and use cases. Data should be well-documented, securely managed, and auditable.

Step 3: Create a Strong Validation and Testing Strategy

Testing should confirm that the AI system performs accurately and consistently. Include stress testing, bias analysis, and real-world scenario validation.

Step 4: Define Post-Market Monitoring Processes

Monitoring device performance after launch is essential. Collect user feedback, error logs, and performance metrics to identify potential issues early.

Step 5: Prepare a Change Management Plan

Since AI models evolve, establish clear rules for updates and revalidation. Use the FDA’s Predetermined Change Control Plan format to explain how algorithm changes will be managed.

Step 6: Use Robust Measurement Controls

Measurement controls are essential for precision and repeatability. For example:

  • Calibration of sensors in wearable devices.
  • Verification of signal accuracy.
  • Tracking software and firmware versions.

Step 7: Focus on Transparency and User Education

AI systems must be understandable to their users. Clear labeling, user guides, and intuitive interfaces help prevent misuse or misinterpretation of data.

What Are the Common Challenges in Meeting FDA’s New Expectations?

Even with clear guidance, AI device developers face unique challenges. Some of the most common include:

  • Underestimating data complexity: High-quality, unbiased data is difficult to obtain, yet essential for reliable AI models.
  • Ignoring post-market requirements: Continuous monitoring is not optional—it’s a core part of lifecycle management.
  • Neglecting transparency: Failing to explain how the AI works can lead to user confusion or regulatory pushback.
  • Inadequate validation: Real-world testing must match or exceed laboratory validation.
  • Weak documentation: Every step—from data collection to model updates—must be traceable and auditable.

By focusing on lifecycle management, documentation, and control systems, companies can overcome these obstacles efficiently.

How Can Manufacturers Stay Competitive Under the New Guidelines?
