The United States Food and Drug Administration (FDA) has been actively engaged in the regulation and supervision of medical devices that are enabled by Artificial Intelligence and Machine Learning (AI/ML). As of October 19, 2023, the FDA has revised its list of these devices, incorporating 171 new entries. This article seeks to provide a comprehensive overview of the current state of AI/ML in medical devices based on the guidelines set forth by the FDA, while also offering insights into what can be expected in the coming year.
Current Landscape
Regulatory Oversight
The FDA is responsible for ensuring that AI/ML-enabled medical devices comply with premarket requirements, with a particular emphasis on their safety and effectiveness. These devices undergo a comprehensive evaluation process, which includes an assessment of their intended use and technological features.
Technological Advancements
AI/ML technologies have become more and more integrated into medical devices, especially in the field of Radiology, followed by Cardiovascular, Neurology, and other specialties. The primary purpose of this technology is to derive valuable insights from the extensive amount of healthcare data available.
Trends in AI/ML Applications
The FDA has noted a steady rise in AI/ML-enabled devices over the years, and it anticipates a significant surge in 2023. The sophistication of machine learning models employed in these devices has also been advancing, with a shift towards more hybrid methodologies.
Remarks on the List of AI/ML-Enabled Medical Devices
Diversity in Medical Specialties
The FDA has provided a diverse list of AI/ML-enabled medical devices, which cover multiple medical specialties. It seems that radiology is the most well-represented field, followed by cardiovascular and neurology. This indicates that AI/ML technologies are being widely utilized in healthcare, although their adoption may vary across different fields.
Increasing Number of Approvals
The FDA has been consistently updating the list, with 171 new entries added as of October 19, 2023. This demonstrates a progressive acceptance and integration of AI/ML technologies in medical devices, aligning with the FDA's projection of a more than 30% increase in such devices in 2023.
Complexity of Models
The devices utilize machine learning models that span from simple to more intricate deep learning models. Some are even employing hybrid approaches, blending various algorithmic methods to accomplish the intended outcomes. This demonstrates the progressive nature of AI/ML technologies and their growing sophistication.
Notable Companies and Innovations
The list contains devices from reputable companies as well as up-and-coming startups. For example, Apple Inc. has a Cardiovascular device that includes an "Irregular Rhythm Notification Feature," and GE Medical Systems is prominently featured in Radiology. This indicates that both established companies and new players are making significant contributions to the progress of this field.

No Large Language Models Yet
As per the latest update, it is interesting to note that no device has been authorized yet which utilizes generative AI or large language models (LLMs). However, considering the rapid advancements in LLM technologies, this could potentially become a promising area for future growth.
Regulatory Compliance
All the devices mentioned in the list have successfully fulfilled the applicable premarket requirements set by the FDA. These requirements include a thorough evaluation of safety and effectiveness, taking into account both the intended use of the device and its technological characteristics. This demonstrates the FDA's unwavering dedication to ensuring that these innovative technologies are not only safe but also effective for public use.
To summarize, the FDA's compilation of AI/ML-enabled medical devices serves as a valuable resource for gaining insights into both current trends and future developments within this rapidly evolving field. It highlights the growing integration of AI/ML technologies in healthcare, their expanding utilization across various medical specialties, and the increasing complexity of algorithms employed in these applications.
Outlook for the Next Year
Based on projected volumes, the FDA expects a 30+% increase in AI/ML-enabled devices in 2023 compared to 2022. While Radiology dominates the list, other fields like Cardiovascular and Neurology are also expected to see an increase in AI/ML applications. The FDA anticipates that the complexity of machine learning models will continue to grow, possibly incorporating large language models (LLMs) and even generative AI in the future.
Conclusion
The FDA plays a crucial role in ensuring the safety and effectiveness of AI/ML-enabled medical devices. With technological advancements and an increasing number of such devices entering the market, the FDA's regulatory framework will continue to evolve. The year 2023 is expected to witness significant growth in this sector, both in terms of the number of devices and the complexity of the AI/ML algorithms employed.
