In the United States, manufacturers face critical regulatory decisions when seeking FDA clearance, as they must determine whether their device can leverage an existing predicate or if it is sufficiently novel to require a different regulatory pathway. The FDA employs a risk‐based system that not only assesses the premarket evidence required for approval, but also emphasizes post‐market surveillance and lifecycle management of AI software functions."}]}, {"components": [{"component_name": "heading", "heading": "Regulatory Pathways: 510(k) Versus De Novo", "level": 2}, {"component_name": "media_gallery", "media": [{"caption": "fda de novo vs 510(k)", "url": "https://operonstrategist.com/wp-content/uploads/2025/02/FDA-De-Novo-vs.-US-FDA-510k-01.jpg", "source_url": "https://operonstrategist.com/fda-de-novo-vs-510k/", "title": null, "s3_key": null, "s3_thumbnail_key": null, "type": "image", "id": 221644, "html": null, "carousel_h5": "fda de novo vs 510(k)", "alt": "fda de novo vs 510(k)"}]}, {"component_name": "paragraph", "paragraph": "For AI‐enabled wearables, two primary FDA clearance pathways are available: the 510(k) and the De Novo routes. The 510(k) process is based on demonstrating substantial equivalence to a legally marketed predicate device. In this process, the new device is compared against an existing device that has already been cleared, meaning that if the similarities in design, intended use, and technological characteristics align, the pathway tends to be faster and less resource intensive. Conversely, if the wearable incorporates novel machine‐learning algorithms or unique interactions that lack a clear predicate, manufacturers may need to pursue the De Novo pathway. The De Novo process essentially establishes a new device classification when general and special controls are sufficient to ensure safety and effectiveness but no predicate exists"}, {"component_name": "paragraph", "paragraph": "The choice between these pathways hinges on the degree of innovation and the presence of a similar device on the market.

Manufacturers must decide between using the 510(k) process, which relies on predicate comparability, and the De Novo pathway, which is tailored for innovative devices lacking similar predecessors. Both pathways demand robust clinical evidence to substantiate claims of safety and effectiveness, with the level of evidence typically higher for devices cleared via De Novo. Post‐market surveillance and a proactive lifecycle management approach – including the use of tools like the Predetermined Change Control Plan – are integral to maintaining device performance and safety in real‐world settings. By addressing these key regulatory considerations, manufacturers can ensure that their AI‐enabled wearable devices not only gain FDA clearance but also continue to deliver safe and effective performance over time."}]}]}
