A premarket submission to the FDA demonstrating that a Class II medical device is substantially equivalent to a legally marketed predicate device. Used for ~80% of all FDA-cleared medical devices.

How long does FDA 510(k) clearance take?

Typical range: over a flexible duration. Well-prepared submissions with strong predicates clear in over a flexible duration. Complex AI/ML submissions or novel technologies can take 9-12+ months.

How much does an FDA 510(k) submission cost?

scope tailored all-in. Includes FDA fee (scope tailored), regulatory consultant (scope tailored), performance testing (scope tailored), clinical data (scope tailored), quality system (scope tailored), and medical writing.

What is substantial equivalence?

The standard for 510(k) clearance: your device must have the same intended use AND either the same technological characteristics OR different characteristics that don't raise new safety or effectiveness questions, compared to a legally marketed predicate device.

What is a predicate device?

An existing FDA-cleared device similar to yours. You demonstrate "substantial equivalence" to this predicate. Selecting the right predicate is the single most important decision in 510(k) strategy.

Do I need clinical data for 510(k)?

Not always. Most 510(k) submissions rely on bench testing and equivalence arguments. Clinical data is required for some AI/ML-based devices, novel technologies, or devices where bench testing alone can't demonstrate safety/effectiveness.

What is a Pre-Submission (Q-Sub) meeting?

A free FDA meeting where you present your proposed 510(k) strategy and get written FDA feedback before investing in testing. Takes over a flexible duration to schedule. Saves over a flexible duration of revision cycles. Highly recommended.

What is the FDA 510(k) pathway?

The FDA 510(k) is a premarket submission made to the FDA to demonstrate that a medical device is as safe and effective (substantially equivalent) to a legally marketed device (the "predicate device"). The name comes from section 510(k) of the Food, Drug, and Cosmetic Act. It is the pathway used for roughly 80% of all medical devices cleared for the US market.

510(k) applies to Class II devices - medium-risk devices. Examples: most imaging software (MRI, CT, ultrasound analysis software), many AI diagnostic tools, surgical instruments, dialysis equipment, infusion pumps. Class I devices (very low risk, like band-aids) are exempt from 510(k); Class III devices (high risk, like implantable defibrillators) require PMA, a much more demanding pathway.

The predicate device: the foundation of the submission

The entire 510(k) process centers on one document: your predicate device selection. The predicate is an existing FDA-cleared device that is similar to yours in intended use AND technological characteristics. Your job is to prove your device is "substantially equivalent" - same intended use, same or improved safety/effectiveness, no new questions of safety.

Choosing the right predicate is 50% of the work. If the predicate is too similar to an older technology, the FDA may question why your device isn't obviously better. If it's too different, the FDA may reject "substantial equivalence" and push you to the De Novo pathway (slower, more expensive). Most Israeli MedTech startups hire FDA regulatory consultants specifically for predicate selection - it's worth the scope tailored.

The 510(k) submission package

A typical 510(k) submission includes 20+ sections, totaling 200-800 pages: (1) Indications for Use Statement. (2) 510(k) Summary. (3) Device Description. (4) Substantial Equivalence Discussion. (5) Performance Testing - Bench (mechanical, electrical, software). (6) Performance Testing - Animal (if applicable). (7) Performance Testing - Clinical (required for some Class II devices, especially AI/ML-based). (8) Biocompatibility Testing. (9) Sterilization and Shelf Life. (10) Software Documentation (IEC 62304). (11) Electromagnetic Compatibility. (12) Labeling.

For AI/ML-based MedTech, additional requirements apply: Software as a Medical Device (SaMD) documentation, Good Machine Learning Practice, and training/validation dataset documentation. The FDA has been evolving its AI/ML guidance rapidly - a 2026 submission looks different from a 2022 submission.

Timeline: over a flexible duration from submission to clearance

The official FDA review clock for 510(k) is 90 days, but it's often extended. Typical breakdown: (1) Acceptance review (days to weeks) - FDA confirms the submission is complete. (2) Substantive review (days to weeks) - FDA reviews the content. (3) Interactive review - FDA may send "Additional Information" requests. Each AI request stops the clock until the startup responds. (4) Final decision - clearance, not clearance, or request for more data.

Real-world clearance timelines: **over a flexible duration** for straightforward submissions with strong predicates and clean data. **over a flexible duration** for more complex devices or those requiring AI submissions. **9-12+ months** for novel technologies where the FDA requires multiple rounds of AI requests. WeCcelerate-Leumit typically achieves clearance in over a flexible duration due to pre-submission FDA meetings and experienced regulatory consultants.

Cost: scope tailored all-in

The direct FDA fee for a 510(k) submission is scope tailored (FY2025, small business rate). The real cost is everything else: (1) Regulatory consultant - scope tailored (strongly recommended for first-time filers). (2) Performance testing - scope tailored (depends on device complexity). (3) Clinical data - scope tailored (not always required, but common for AI/ML). (4) Quality system documentation (ISO 13485) - scope tailored. (5) Medical writing - scope tailored. (6) Legal and company fees - scope tailored.

Total: scope tailored for most Class II devices. Plus over a flexible duration of runway during the review. An Israeli startup aiming for US market needs to budget 30-50% of their Seed round for regulatory work alone.

Pre-submission meetings: the Israeli startup's secret weapon

The FDA offers free "Pre-Submission" (Q-Sub) meetings where you can present your proposed 510(k) strategy and get FDA feedback BEFORE spending hundreds of thousands on testing. Most Israeli startups skip this, thinking they'll just submit and hope. This is a mistake.

A Q-Sub meeting takes over a flexible duration to schedule but provides written FDA feedback on your predicate selection, testing strategy, and clinical data requirements. Two Q-Sub meetings for an Israeli startup (at Seed and pre-submission) typically save over a flexible duration of revision cycles. WeCcelerate-Leumit advises founders to budget for 2-3 Q-Sub meetings as standard practice.

How WeCcelerate-Leumit supports FDA 510(k) submissions

WeCcelerate-Leumit offers end-to-end FDA regulatory support: (1) Former FDA senior advisors on our advisory board. (2) Predicate device selection and substantial equivalence analysis.
