When preparing a 510(k) for a device that introduces new technological features compared to its predicate—such as an orthopedic implant with a novel surface coating or a diagnostic software with a new...

When preparing a 510(k) submission for a Class II device that incorporates an incremental but significant technological change, such as an orthopedic implant with a novel surface material designed to ...

For a manufacturer of a Class I medical device, such as a non-sterile tongue depressor or an elastic bandage, that is exempt from 510(k) premarket notification, what constitutes a robust compliance fr...

For manufacturers of a 510(k)-cleared device, the decision between documenting a modification with a 'Letter to File' versus submitting a new 510(k) is a recurring challenge. Beyond the foundational r...

When a sponsor's new medical device incorporates significantly different technological characteristics compared to the chosen predicate—for example, a diagnostic imaging device using a novel AI/ML alg...

For a medical device company, particularly a startup, successfully navigating the FDA’s Small Business Determination (SBD) process is a critical step to manage costs associated with MDUFA user fees. S...

When preparing a 510(k) submission for a device with technological differences from its predicate—such as an electrosurgical generator featuring a modified energy delivery algorithm and a new user int...

When pursuing a 510(k) submission using a 'split predicate' approach—combining key features from two or more legally marketed devices—how can a sponsor construct a robust substantial equivalence argum...

For a sponsor preparing a 510(k) for a Class II device, such as a software-enabled cardiac monitor or an integrated continuous glucose monitoring system (iCGM) under 21 CFR 862.1355, a critical challe...

When preparing a 510(k) for a connected medical device, such as a networked patient monitor or a cloud-based SaMD, how can sponsors develop a cybersecurity documentation package that forms a cohesive,...

When a sponsor receives a hold on their 510(k) submission, how can they distinguish between a Refuse to Accept (RTA) hold and an Additional Information (AI) request, and what are the critical differen...

For manufacturers of 510(k)-exempt Class I devices, such as elastic bandages or tongue depressors, the term "General Controls" can be misleadingly simple. While these devices do not require premarket ...

For a Class II medical device with clear technological differences from its chosen predicate—such as an orthopedic implant with a novel biocompatible coating or an infusion pump with significant softw...

When preparing a 510(k) submission for a device with technological differences from its predicate—such as an infusion pump incorporating a new user interface and different patient-contacting materials...

When developing a combination product, such as an antimicrobial-coated catheter or a pre-filled injector pen, how should a sponsor definitively determine the product's Primary Mode of Action (PMOA) to...

Beyond a surface-level check against the FDA's Refuse to Accept (RTA) checklist, what systematic, in-depth review process can a sponsor implement to proactively identify and resolve common administrat...

When a sponsor develops a novel medical device by creating a hybrid system—for example, an electrosurgical device that combines a unique energy waveform from Predicate A with an advanced tissue-monito...

For a company developing a digital health product, such as a wearable sensor that analyzes sleep data, what is a robust analytical framework for determining whether the product is a regulated medical ...

For manufacturers of network-connected medical devices, such as a Wi-Fi-enabled patient monitor, what are the essential components of a robust cybersecurity documentation package for a 510(k) submissi...

How can a manufacturer of a lower-risk device, such as a Class I handheld diagnostic instrument or a Class II software-based patient monitoring tool, strategically implement a "right-sized" Quality Ma...
