#404: MedTech 101: What You Need to Know About the Medical Device Industry

Are you new to the medical device industry—or mentoring someone who is? In this foundational episode of the Global Medical Device Podcast, host Etienne Nichols sits down with Sara Adams and Chris Rush from Greenlight Guru to deliver a MedTech 101 masterclass.

They unpack the roles, regulations, and realities of medical device development in a heavily regulated space. From defining what actually counts as a medical device to navigating FDA classifications and global regulations, the trio offers practical insights, industry analogies, and personal war stories that make this episode as entertaining as it is educational. Whether you’re in R&D, marketing, clinical, or quality, this is the episode to bookmark and share with every new hire.

Quotes

“Just because you don’t call it a medical device doesn’t mean the FDA agrees with you.” – Sarah Adams

This quote highlights a key regulatory pitfall: your marketing claims, not just your label, determine if the FDA considers your product a medical device.

“A 510(k) is like someone checking your wristband at the door—you’re cleared to go in. A PMA? That’s a locked door and you need full approval to enter.” – Chris Rush

A memorable analogy that demystifies the difference between FDA clearance and approval pathways.

Top Takeaways

Labeling + Intended Use = Regulatory Trigger

Whether it’s software or a simple tool, if your product makes medical claims or supports medical decision-making, it may fall under FDA or other international regulatory oversight.

Regulatory Pathways Are Tied to Risk and Novelty

Know the difference between a 510(k), De Novo, and PMA. Class II “me-too” devices may avoid clinical trials, while Class III and novel devices usually require significant evidence.

Understand Design Controls Early

Reverse-engineering documentation late in development is risky and inefficient. Start early with user needs and build forward through the five pillars: inputs, outputs, verification, and validation.

Cross-functional Understanding Prevents Compliance Gaps

Marketing, clinical, and R&D all influence regulatory standing. Even social media likes can trigger off-label scrutiny—every department needs to understand their regulatory impact.

Reading Regulations Is Not Optional

A strong regulatory foundation is key to faster development, better audits, and smoother market access. Resources like 21 CFR Part 820 and ISO 13485 are surprisingly readable and essential.

MedTech 101: Key Concepts Explained

Design Controls = Your Blueprint for Safe Innovation

Think of design controls as a recipe:

• User Needs = what the customer is hungry for
• Design Inputs = what you plan to give the customer
• Design Outputs = the finished dish (specs)
• Verification = checking the dish matches the recipe
• Validation = confirming the customer loves it

FDA Classes: Think Risk Levels

• Class I – Low risk: toothbrushes, bandages
• Class II – Moderate risk: catheters, infusion pumps (often 510(k))
• Class III – High risk: pacemakers, implants (typically PMA)

510(k) vs. De Novo vs. PMA – Simplified

• 510(k) – You’re like someone else
• De Novo – You’re new, but not high-risk
• PMA – You’re new and high-risk = prove everything
