SAFERTOS® provides developers with a responsive, robust, deterministic, embedded Real Time Operating System (RTOS). It contains features needed for the development of medical devices, and the Design History File provides all the documentation required for an easy route to achieving certification of SAFERTOS once integrated within a medical device.
By specifically supporting the needs of medical device developers, SAFERTOS can greatly reduce program risks, lower development costs and shorten the time to market for medical device products.

Case Study: Ottobock
Ottobock chose SAFERTOS® to replace all of their custom embedded software across their microprocessor controlled lower limb prostheses. They have this to say about WITTENSTEIN high integrity systems:
SAFERTOS is very high quality, and the support from the engineers and the sales staff has been excellent. I would strongly recommend them

Reduced Certification Time & Costs for Medical Submissions
SAFERTOS® supports FDA 510(k) class III device submissions and IEC 62304 class C certifications.
The SAFERTOS Safety Manual clearly details how to install and integrate SAFERTOS into a medical device development environment. Following the concise instructions contained within the Safety Manual preserves the verification and validation already performed, and removes the need for expensive and prolonged re-testing on the target hardware.
- FDA 510(k) class III medical device submissions
- IEC 62304 class C certification
- Independently assessed by TÜV SÜD for IEC 62304 Class C compliance
- No re-testing required
“SAFERTOS has proven to be a good choice for implementing safety-critical functions in medical devices. Not only because of the reliability of the software, but also because of the documentation and certification that are available which reduces the effort of the necessary SOUP validation.“
– Matthias Hölzer-Klüpfel, Independent Consultant & Co-Founder of International Certified Professional for Medical Software Board e.V.

Case Study: The world’s first ‘Warmed Liver’ transplant was carried out successfully, using technology devised by OrganOx with SAFERTOS® at its core.
ISO 14971 Risk Management for Medical Devices
The SAFERTOS® high integrity design life cycle implements a risk management system that, where applicable, complies with ISO 14971:2009 “Application of risk management to medical devices”.
This provides reassurance that SAFERTOS has been designed to meet the safety requirements for use within a medical device. It also allows for the easy integration of the Design History File into a medical device development environment.

SAFERTOS in Multicore Medical Devices
SAFERTOS® enables dual and multicore/processor medical device designers to create seamless, mixed safety criticality designs quickly and efficiently. Due to its small size and its safety critical credentials, SAFERTOS is ideally suited for use on the primary core. This allows the system to boot and configure itself securely before enabling other cores that could run non-critical applications such as Linux to implement web servers and WiFi connections.
In a multicore environment, SAFERTOS is typically used on cores implementing safety critical functionality, or on cores providing monitoring/verification of the primary function. Due to its high safety classification, SAFERTOS can safely be used on both primary and monitoring cores, removing the need to use differential software.

Beyond SAFERTOS for Medical Devices
- SAFERTOS CORE: for medical devices that only need to consider safety and don’t require full certification.
- Safety Component: bring greater robustness to safety critical medical designs. WHIS Safety components are available with a Design History File supporting certification to medical standards.
- Board Support Packages and Drivers: delivered either as commercial grade components, or with a Design History File supporting medical submissions and certifications.
- Training: maximise the use of your RTOS and increase development proficiency by attending one of our comprehensive training courses.
- Peer review services: sometimes just a few hours of consultancy to review a preliminary medical design, and check the approach being taken is correct, can deliver significant benefits to the outcome of a project.
- Consultancy services: designed to support our medical device customers, allowing us to share our knowledge and experience of medical device development to help optimise the final design, improve the design processes and smooth the route to medical device certification.
