S1 · Idea / early design

Regulatory pathway brief

Which product code, which predicate, which pathway — read from every cleared device that came before yours.

The stage

Idea to early design: the device exists on paper or as a prototype.

The question this week

“Where does our device fit, and what has the FDA already cleared that looks like it?”

Who it is for

  • Founders and CTOs of AI device start-ups without a regulatory lead
  • Teams choosing between a 510(k) and a De Novo request
  • Anyone preparing a fundraise who must explain the regulatory route

The problem

  • You do not know which product code your device falls under, and the FDA databases do not answer the question directly.
  • Choosing a predicate means reading dozens of clearance summaries; a poor choice is often found late.
  • Nobody near you can say what cleared devices in your code had to show, or what was recalled.

You send

  • A one-page description of the device
  • Its intended use and indications, in a sentence or two
  • Anything you already know about similar devices

Under a signed confidentiality agreement, held on the consultant’s machine only and deleted by a date you agree.

You receive

  • The product codes considered, and why each was or was not chosen
  • The predicate candidates in your code, ordered by how often later clearances cite them, with each one's lineage
  • The code's record: how many devices cleared, what their summaries state, how long past reviews took, and recalls with their root causes
  • A written reading of six pathway questions — predicate, technological differences, De Novo, Pre-Submission, change-control plan, and what to plan around
  • Every statement footnoted to an FDA document page or to our reading of it

Format: PDF and Word, every statement footnoted. Typical turnaround: about a week from the call.

What it is not

  • A determination of your device's classification — only the FDA makes one
  • A statement about the FDA's decision on any submission

The FDA decides. Every deliverable says so on its cover.

What usually comes next

S2, when you plan the validation study.
