MP3•Episode home

In this episode of Let’s Combinate, host Subhi Saadeh is joined by Mark Burchnall, Director of Engineering at PSN Labs, to break down the evolving role of mechanical modeling and simulation in medical device and combination product development.

Mark, an expert in mechanical modeling & finite element analysis (FEA) and a licensed professional engineershares how modeling can dramatically reduce prototyping cycles, support regulatory submissions, and lower test burden when applied appropriately.

Mark disucsses:

Why modeling is often misunderstood

When it can replace (or complement) traditional testing

What makes a model “credible” under ASME V&V 40

How to build internal processes for regulatory-grade models

And what every skeptic (or startup) needs to know before adopting modeling
