Medical device manufacturers face growing pressure to keep legacy platforms viable in a rapidly evolving technical and regulatory landscape.
For many established devices, ensuring that proven, safety‑critical systems can continue to be manufactured, supported and trusted for years to come is a challenge that must be managed with the same vigour as the development of new products.
Two issues consistently sit at the heart of this challenge: component obsolescence and regulatory change. Individually, each can disrupt product lifecycles. Together, they can threaten supply continuity, affect existing devices, and undermine clinician confidence, if not addressed in a structured and evidence‑led way.
Why obsolescence is no longer a background issue
Electronic components rarely age at the same pace as medical devices. Semiconductors, sensors and sub‑assemblies may reach end‑of‑life within a few years, whilst medical systems might be expected to remain in clinical service for decades. Ideally, these parts would simply be replaced, but when critical components become unavailable, manufacturers face difficult choices: last‑time buys, stop‑gap substitutions or more fundamental redesign.
In safety‑critical devices, these decisions cannot be made in isolation. Any change has the potential to trigger extensive re‑verification, additional risk analysis, and, in some cases, engagement with notified bodies or regulators. What might appear to be a supply‑chain issue quickly becomes a systems engineering and regulatory challenge.
Regulatory expectations continue to move
International standards governing medical electrical equipment and software continue to evolve. Devices approved under earlier versions of standards may still be safe and effective, but manufacturers are expected to demonstrate continued compliance when changes are introduced.
This creates a tension for long‑lifecycle products. Manufacturers must modernise parts of the system to address obsolescence or performance expectations, whilst preserving the safety integrity, architecture and clinical behaviour that users trust.
Modernising without undermining trust
During a recent collaboration with Inspiration Healthcare the team at eg technology illustrated how these challenges can be addressed in practice.
Inspiration Healthcare identified the need to update a critical monitoring sub‑system within their SLE6000 neonatal ventilator platform. Several electronic components within the existing design had reached end‑of‑life, creating long‑term supply risks for both new production and servicing devices already deployed in neonatal units worldwide. At the same time, regulatory expectations had moved on since the platform was first developed.
The goal was not to redesign the ventilator, but to modernise a safety‑critical sub‑system in a way that maintained continuity of manufacture, service and clinical support.
A system level approach to change
Rather than treating obsolescence as a component swap exercise, the project took a system‑level view. The monitoring sub‑system was redeveloped to clearly separate safety‑critical and non‑critical functions, supporting predictable behaviour and robust risk management. This approach helped ensure that changes introduced to address component availability did not introduce unintended interactions elsewhere in the system.
Crucially, the work was carried out in close collaboration with Inspiration Healthcare’s in‑house engineering team, enabling detailed understanding of legacy design decisions, clinical use and regulatory history. This collaborative model is often essential when working with mature platforms where knowledge has been built up over many years.
Designing for future resilience
Addressing today’s obsolescence is only part of the challenge. Effective updates should leave the system better placed to respond to future change.
In this case, the modernised hardware was designed to support continued manufacture, long‑term serviceability, and alignment with current international medical device standards. By integrating the new sub‑system seamlessly into the wider ventilator architecture, the platform was able to move forward without fragmenting the installed base or increasing operational burden for clinical teams.
Key lessons for MedTech teams
Projects like this highlight several broader lessons for MedTech organisations managing legacy devices:
Primarily, obsolescence planning needs to be proactive. Waiting until components become unavailable limits options and increases commercial and regulatory risk.
Secondly, regulatory change should be considered alongside technical updates from the outset. Treating compliance as an afterthought often leads to rework and delay.
Finally, preserving clinical confidence matters. For devices used in safety‑critical settings, continuity of behaviour and interface familiarity can be just as important as technical upgrades.
Moving forward
For many MedTech organisations, the future will involve maintaining and evolving existing platforms as much as launching new ones. Addressing component obsolescence and regulatory change in a structured, system‑aware way can help extend product lifecycles, protect patients and safeguard investment.
At eg technology, we work with MedTech teams to navigate these challenges thoughtfully, combining engineering rigour with a deep understanding of safety‑critical and regulatory environments. The Inspiration Healthcare project demonstrates how careful modernisation can strengthen a proven platform, without compromising the trust it has earned.
