Medical device design consultancy TTP Plc has released a new technical guide that explores a faster, more scalable approach to evaluating MRI safety for active implantable medical devices (AIMDs), particularly systems with long conductive leads where RF-induced heating can present a significant development challenge.
The piece examines MRI compatibility within the ISO 10974 framework, focusing on Tier 3 assessment and the determination of transfer functions. It outlines how frequency-domain computational modelling can enable faster lead iteration, reduce reliance on repeated phantom testing and provide earlier insight into MRI safety during development.
TTP’s Neurotechnology team explores how transfer functions can be modelled in minutes per case, allowing design changes to be evaluated earlier and with fewer physical prototypes. It also considers where simulation can replace exploratory testing and where experimental validation remains essential.
The publication reflects the growing expectation for broader MRI access for implant recipients, including full-body MRI access, and the need to address MRI compatibility earlier in the development process.
The e-book, A smarter way to design MRI-safe implants: Streamlining Tier 3 modelling for MRI compatibility design, will be relevant to AIMD developers looking to de-risk MRI safety earlier and accelerate progress towards MRI-conditional labelling.

TTP helps MedTech teams solve tough scientific and engineering challenges where the solution isn't always obvious.
With 300+ engineers, scientists and designers on one campus, we reduce risk early by bringing together multidisciplinary teams with the expertise and autonomy to make decisions quickly, develop solutions with fewer iterations and keep programmes moving.
With extensive facilities including cleanrooms, labs and small-batch manufacturing, we design, build and de-risk, from first principles through to clinical feasibility and transfer to manufacture.
We are 100% employee owned, technology- and factory-agnostic, meaning our recommendations are guided by what's right for the product, not by equity or partnerships. The result is technology designed not just to work in a prototype, but to perform reliably, scale effectively and create a clear path to commercial viability.
