Traversing TRLs in MedTech Development: A Step-by-Step Journey
The journey of MedTech hardware products from conception to market availability is meticulously charted through Technology Readiness Levels (TRLs). Each level signifies a critical stage in the development of medical devices, ensuring safety, efficacy, and market readiness. Here is a detailed exploration of each TRL in the context of MedTech hardware products.
- TRL1 – Define Basic Properties: The journey begins with defining the basic properties and capabilities of the proposed medical device. This stage involves conceptualizing what the device will do and its underlying technology.
- TRL2 – Analytical Study: Researchers conduct analytical studies to understand how the conceptualized device will work. This includes theoretical analysis and design studies.
- TRL3 – Proof of Concept: At this stage, a proof of concept is developed. This involves creating initial models or simulations to demonstrate the feasibility of the device.
- TRL4 – Pre-Prototype: Development progresses to creating a pre-prototype of the device, which is an early version designed to test the basic concept in a non-clinical setting.
- TRL5 – Pre-Prototype Tested in Lab: The pre-prototype undergoes rigorous testing in a laboratory setting. This testing aims to evaluate the device’s functionality and gather data for further development.
- TRL6 – Prototype Tested in Relevant Environment: A more refined prototype is developed and tested in an environment that closely replicates real-world conditions where the device will be used.
- TRL7 – Approved Prototype: The prototype reaches a stage where it is approved for final development. This typically involves passing certain regulatory checks and validations.
- TRL8 – Pre-Serial Manufacturing: The device moves into pre-serial manufacturing, where small batches are produced to ensure manufacturing processes are ready for full-scale production.
- TRL9 – Product on Market: The final stage, where the MedTech hardware product is fully developed, manufactured, and available on the market. It has passed all regulatory approvals and is ready for use in healthcare settings.
MedTech TRLs
The progression from TRL1 to TRL9 in MedTech hardware product development is a methodical and critical process, ensuring that medical devices meet the highest standards of quality and safety.
